### Added
+- Added Polish support to `AWSTranscribeSTTService`.
+
+- Added new frames `FrameProcessorPauseFrame` and `FrameProcessorResumeFrame`
+ which allow pausing and resuming frame processing for a given frame
+ processor. These are control frames, so they are ordered. Pausing frame
+ processor will keep old frames in the internal queues until resume takes
+ place. Frames being pushed while a frame processor is paused will be pushed to
+ the queues. When frame processing is resumed all queued frames will be
+ processed in order. Also added `FrameProcessorPauseUrgentFrame` and
+ `FrameProcessorResumeUrgentFrame` which are system frames and therefore they
+ have high priority.
+
+- Added a property called `has_function_calls_in_progress` in
+ `LLMAssistantContextAggregator` that exposes whether a function call is in
+ progress.
+
+### Changed
+
+- Upgraded `daily-python` to 0.19.3.
+
+### Fixed
+
+- Fixed an issue with `GroqTTSService` where it was not properly parsing the
+ WAV file header.
+
+- Fixed an issue with `GoogleSTTService` where it was constantly reconnecting
+ before starting to receive audio from the user.
+
+- Fixed an issue where `GoogleLLMService`'s TTFB value was incorrect.
+
+### Other
+
+- Rename `14e-function-calling-gemini.py` to `14e-function-calling-google.py`.
+
+## [0.0.71] - 2025-06-10
+
+### Added
+
+- Adds a parameter called `additional_span_attributes` to PipelineTask that
+ lets you add any additional attributes you'd like to the conversation span.
+
+### Fixed
+
+- Fixed an issue with `CartesiaSTTService` initialization.
+
+## [0.0.70] - 2025-06-10
+
+### Added
+
+- Added `ExotelFrameSerializer` to handle telephony calls via Exotel.
+
+- Added the option `informal` to `TranslationConfig` on Gladia config.
+ Allowing to force informal language forms when available.
+
+- Added `CartesiaSTTService` which is a websocket based implementation to
+ transcribe audio. Added a foundational example in
+ `13f-cartesia-transcription.py`
+
+- Added an `websocket` example, showing how to use the new Pipecat client
+ `WebsocketTransport` to connect with Pipecat `FastAPIWebsocketTransport` or
+ `WebsocketServerTransport`.
+
+- Added language support to `RimeHttpTTSService`. Extended languages to include
+ German and French for both `RimeTTSService` and `RimeHttpTTSService`.
+
+### Changed
+
+- Upgraded `daily-python` to 0.19.2.
+
+- Make `PipelineTask.add_observer()` synchronous. This allows callers to call it
+ before doing the work of running the `PipelineTask` (i.e. without invoking
+ `PipelineTask.set_event_loop()` first).
+
+- Pipecat 0.0.69 forced `uvloop` event loop on Linux on macOS. Unfortunately,
+ this is causing issue in some systems. So, `uvloop` is not enabled by default
+ anymore. If you want to use `uvloop` you can just set the `asyncio` event
+ policy before starting your agent with:
+
+```python
+asyncio.set_event_loop_policy(uvloop.EventLoopPolicy())
+```
+
+### Fixed
+
+- Fixed an issue with various TTS services that would cause audio glitches at
+ the start of every bot turn.
+
+- Fixed an `ElevenLabsTTSService` issue where a context warning was printed
+ when pushing a `TTSSpeakFrame`.
+
+- Fixed an `AssemblyAISTTService` issue that could cause unexpected behavior
+ when yielding empty `Frame()`s.
+
+- Fixed an issue where `OutputAudioRawFrame.transport_destination` was being
+ reset to `None` instead of retaining its intended value before sending the
+ audio frame to `write_audio_frame`.
+
+- Fixed a typo in Livekit transport that prevented initialization.
+
+## [0.0.69] - 2025-06-02 "AI Engineer World's Fair release" ✨
+
+### Added
+
+- Added a new frame `FunctionCallsStartedFrame`. This frame is pushed both
+ upstream and downstream from the LLM service to indicate that one or more
+ function calls are going to be executed.
+
+- Added LLM services `on_function_calls_started` event. This event will be
+ triggered when the LLM service receives function calls from the model and is
+ going to start executing them.
+
+- Function calls can now be executed sequentially (in the order received in the
+ completion) by passing `run_in_parallel=False` when creating your LLM
+ service. By default, if the LLM completion returns 2 or more function calls
+ they run concurrently. In both cases, concurrently and sequentially, a new LLM
+ completion will run when the last function call finishes.
+
+- Added OpenTelemetry tracing for `GeminiMultimodalLiveLLMService` and
+ `OpenAIRealtimeBetaLLMService`.
+
+- Added initial support for interruption strategies, which determine if the user
+ should interrupt the bot while the bot is speaking. Interruption strategies
+ can be based on factors such as audio volume or the number of words spoken by
+ the user. These can be specified via the new `interruption_strategies` field
+ in `PipelineParams`. A new `MinWordsInterruptionStrategy` strategy has been
+ introduced which triggers an interruption if the user has spoken a minimum
+ number of words. If no interruption strategies are specified, the normal
+ interruption behavior applies. If multiple strategies are provided, the first
+ one that evaluates to true will trigger the interruption.
+
- `BaseInputTransport` now handles `StopFrame`. When a `StopFrame` is received
the transport will pause sending frames downstream until a new `StartFrame` is
received. This allows the transport to be reused (keeping the same connection)

`DailyTransport.stop_transcription()` to be able to start and stop Daily
transcription dynamically (maybe with different settings).
+### Changed
+
+- Reverted the default model for `GeminiMultimodalLiveLLMService` back to
+ `models/gemini-2.0-flash-live-001`.
+ `gemini-2.5-flash-preview-native-audio-dialog` has inconsistent performance.
+ You can opt in to using this model by setting the `model` arg.
+
+- Function calls are now cancelled by default if there's an interruption. To
+ disable this behavior you can set `cancel_on_interruption=False` when
+ registering the function call. Since function calls are executed as tasks you
+ can tell if a function call has been cancelled by catching the
+ `asyncio.CancelledError` exception (and don't forget to raise it again!).
+
+- Updated OpenTelemetry tracing attribute `metrics.ttfb_ms` to `metrics.ttfb`.
+ The attribute reports TTFB in seconds.

+
+- Fixed an issue with the `OpenAILLMContext` where non-Roman characters were
+ being incorrectly encoded as Unicode escape sequences. This was a logging
+ issue and did not impact the actual conversation.

This repository contains examples for building intelligent phone chatbots using AI for various use cases including:
-- **Simple dial-in**: Basic incoming call handling
-- **Simple dial-out**: Basic outgoing call handling
-- **Voicemail detection**: Bot calls a number, detects if it reaches voicemail or a human, and responds appropriately
-- **Call transfer**: Bot handles initial customer interaction and transfers to a human operator when needed
+- **daily-pstn-dial-in**: Basic incoming call handling
+- **daily-pstn-dial-out**: Basic outgoing call handling
+- **daily-twilio-sip-dial-in**: Basic incoming call handling using Daily SIP + Twilio
+- **daily-twilio-sip-dial-out**: Basic outgoing call handling using Daily SIP + Twilio
+- **daily-pstn-simple-voicemail-detection**: Voicemail detection Bot. Bot calls a number, detects if it reaches voicemail or a human, and responds appropriately
+- **daily-pstn-advanced-voicemail-detection**: A more advanced example of the voicemail detection bot. Utilises multiple pipelines. The first pipeline uses a much simpler, faster and cheaper LLM to detect the voicemail machine. Then switches to a more powerful LLM if it needs to have a conversation with a user. You should use this one if you want to use different LLMs for different tasks, it also shows how to do audio input for one LLM (multimodal LLM) and then STT for the other one. Switching out methods of sending data to the LLM
+- **daily-pstn-simple-call-transfer**: Bot handles initial customer interaction and transfers to a human operator when needed
## Architecture Overview
These examples use the following components:
- 🔁 **Transport**: Daily WebRTC
-- 💬 **Speech-to-Text**: Deepgram via Daily transport
+- 💬 **Speech-to-Text**: Deepgram via Daily transport, or via separate Deepgram service
- 🤖 **LLMs**: Each example uses a specific LLM (OpenAI GPT-4o or Google Gemini)
+- 📞 **SIP/PSTN**: Examples either use Daily PSTN or SIP with a SIP provider such as Twilio
- 🔉 **Text-to-Speech**: Cartesia
-## Getting Started

### Phone Number Provider: Daily vs Twilio
If you're starting from scratch, we recommend using Daily to provision phone numbers alongside Daily as a transport for simplicity (this provides automatic call forwarding).
If you already have Twilio numbers and workflows, you can connect them to your Pipecat bots with some additional configuration (`on_dialin_ready` and using the Twilio client to trigger forwarding).
-Most examples in this repository show how to use Daily for dial-in/dial-out operations.
-
-## Running the Examples
-
-### 1. Start the Bot Runner Service
-
-The bot runner handles incoming requests and manages bot processes:
-
-```shell
-python bot_runner.py --host localhost
-```
-
-### 2. Create a Public Endpoint with ngrok
-
-Start ngrok to create a public URL for your local server:
-
-```shell
-ngrok http --domain yourdomain.ngrok.app 7860
-```
-
-## Example 1: Simple Dial-in
-
-This example demonstrates basic handling of incoming calls without additional features like call transfer.
-
-### Testing in Daily Prebuilt (No Actual Phone Calls)
-
-```shell
-curl -X POST "http://localhost:7860/start" \
- -H "Content-Type: application/json" \
- -d '{
- "config": {
- "simple_dialin": {
- "testInPrebuilt": true
- }
- }
- }'
-```
-
-This returns a Daily room URL where you can test the bot's basic conversation capabilities.
-
-## Example 2: Simple Dial-out
-
-This example demonstrates basic handling of outgoing calls without additional features like voicemail detection.
-
-### Testing in Daily Prebuilt (No Actual Phone Calls)
-
-```shell
-curl -X POST "http://localhost:7860/start" \
- -H "Content-Type: application/json" \
- -d '{
- "config": {
- "simple_dialout": {
- "testInPrebuilt": true
- }
- }
- }'
-```
-
-This returns a Daily room URL where you can test the bot's basic conversation capabilities.
-
-### Making Actual Phone Calls
-
-```shell
-curl -X POST "http://localhost:7860/start" \
- -H "Content-Type: application/json" \
- -d '{
- "config": {
- "dialout_settings": [{
- "phoneNumber": "+12345678910"
- }],
- "simple_dialout": {
- "testInPrebuilt": false
- }
- }
- }'
-```
-
-## Example 3: Voicemail Detection
-
-This example demonstrates a bot that can dial out to a phone number, detect whether it reached a human or voicemail system, and respond appropriately.
-
-### How It Works
-
-1. Bot dials a phone number
-2. Bot listens to determine if it's connected to a person or voicemail
-3. If it detects voicemail, it leaves a predefined message and hangs up
-4. If it detects a human, it engages in conversation
-
-### Testing in Daily Prebuilt (No Actual Phone Calls)
-
-To test without making actual phone calls:
-
-```shell
-curl -X POST "http://localhost:7860/start" \
- -H "Content-Type: application/json" \
- -d '{
- "config": {
- "voicemail_detection": {
- "testInPrebuilt": true
- }
- }
- }'
-```
-
-This will return a Daily room URL you can use to test the bot in the browser.
-
-### Making Actual Phone Calls
-
-To have the bot dial out to a real phone number:
-
-```shell
-curl -X POST "http://localhost:7860/start" \
- -H "Content-Type: application/json" \
- -d '{
- "config": {
- "dialout_settings": [{
- "phoneNumber": "+12345678910"
- }],
- "voicemail_detection": {
- "testInPrebuilt": false
- }
- }
- }'
-```
-
-> **Note:** To enable dial-out capabilities, you must first:
->
-> 1. Contact [help@daily.co](mailto:help@daily.co) to enable dial-out for your domain
-> 2. Purchase a phone number to dial out from
-> 3. Ensure rooms have dial-out enabled (the bot runner handles this)
-> 4. Use an owner token for the bot (also handled by the bot runner)
-
-## Example 4: Call Transfer
-
-This example demonstrates a bot that handles initial customer interaction and can transfer the call to a human operator when requested.
-
-### How It Works
-
-1. Customer calls in and speaks with the bot
-2. When the customer asks for a supervisor/manager, the bot initiates a transfer
-3. The bot dials out to an appropriate operator
-4. When the operator joins, the bot summarizes the conversation
-5. The bot remains silent while operator and customer talk
-6. When the operator leaves, the bot resumes handling the call
-
-### Testing in Daily Prebuilt (No Actual Phone Calls)
-
-```shell
-curl -X POST "http://localhost:7860/start" \
- -H "Content-Type: application/json" \
- -d '{
- "config": {
- "call_transfer": {
- "mode": "dialout",
- "speakSummary": true,
- "storeSummary": false,
- "operatorNumber": "+12345678910",
- "testInPrebuilt": true
- }
- }
- }'
-```
-
-This returns a Daily room URL. In the room, the expected flow is:
-
-1. Join the room and speak with the bot
-2. Ask to speak with a manager/supervisor
-3. The bot will add the "operator" to the call
-4. The bot will summarize the conversation and then go silent
-5. To simulate the operator, you can mute yourself in Daily Prebuilt and speak as if you're the operator
-6. When finished, have the "operator" leave the call
-7. The bot will resume speaking and can recall details from the conversation
-8. End the call by closing Daily Prebuilt or telling the bot you're done
-
-### Using with Real Phone Calls
-
-For incoming calls from customers, Daily will send a webhook to your `/start` endpoint. This webhook contains:
-
-```json
-{
- "From": "+CALLERS_PHONE",
- "To": "$PURCHASED_PHONE",
- "callId": "callid-read-only-string",
- "callDomain": "callDomain-read-only-string"
-}
-```
-
-The system will:
-
-1. Identify the customer based on their phone number
-2. Determine the appropriate operator to contact
-3. Customize the bot's behavior based on transfer settings
-
-#### Operator Assignment
-
-The `call_connection_manager.py` file contains mappings for:
-
-1. `CUSTOMER_MAP`: Links phone numbers to customer names
-2. `OPERATOR_CONTACT_MAP`: Contains operator contact information
-3. `CUSTOMER_TO_OPERATOR_MAP`: Defines which operators should handle which customers
-
-You can customize these mappings or integrate with your existing customer database.
-
-## Configuration Options
-
-### Request Body Structure
-

-### Notes:
-
-- `dialin_settings` is typically populated automatically from webhook data for incoming calls
-- `dialout_settings` must be specified manually for outgoing calls
-- `operatorNumber` is specified within the `call_transfer` object (`"call_transfer": {"operatorNumber": "+1234567890", ...}`)
-- `testInPrebuilt` is specified within the bot type object (e.g., `"call_transfer": {"testInPrebuilt": true, ...}`)
-- For call transfers, `operatorNumber` must be provided to specify which operator to dial. If it is not provided, we will base it off of the operator map in call_connection_manager.py
-- In test mode (`testInPrebuilt: true`), some requirements are relaxed to allow testing in Daily Prebuilt
-- Multiple customers to dial out to can be specified by providing an array of objects in `dialout_settings`
-- Bot types are mutually exclusive - you cannot combine multiple bot types in a single configuration

## Deployment
@@ -518,61 +44,24 @@ We also have a great, easy to use quickstart guide here: https://docs.pipecat.da
Each example in this repository is implemented with a specific LLM provider:
-- **Simple dial-in**: Uses OpenAI
-- **Simple dial-out**: Uses OpenAI
-- **Voicemail detection**: Uses Google Gemini
-- **Call transfer**: Uses OpenAI
+- **daily-pstn-dial-in**: Uses OpenAI
+- **daily-pstn-dial-out**: Uses OpenAI
+- **daily-twilio-sip-dial-in**: Uses OpenAI
+- **daily-twilio-sip-dial-out**: Uses OpenAI
+- **daily-pstn-simple-voicemail-detection**: Uses Google Gemini Flash 2.0
+- **daily-pstn-simple-voicemail-detection**: Uses Google Gemini Flash Lite 2.0 and Flash 2.0
+- **daily-pstn-simple-call-transfer**: Uses OpenAI
If you want to implement one of these examples with a different LLM provider than what's provided:
-- To implement **call_transfer** with **Gemini**, reference the `voicemail_detection.py` file for how to structure LLM context, function calling, and other Gemini-specific implementations.
-- To implement **voicemail_detection** with **OpenAI**, reference the `call_transfer.py` file for OpenAI-specific implementation details.
+- To implement **call_transfer** with **Gemini**, reference the `bot.py` file inside the voicemail detection example for how to structure LLM context, function calling, and other Gemini-specific implementations.
+- To implement **voicemail_detection** with **OpenAI**, reference the `bot.py` file inside the call_transfer example for OpenAI-specific implementation details.
The key differences between implementations involve how context is managed, function calling syntax, and message formatting. Looking at both implementations side-by-side provides a good template for adapting any example to your preferred LLM provider.
## Customizing Bot Prompts
-All examples include default prompts that work well for standard use cases. However, you can customize how the bot behaves by providing your own prompts in the request body.
-
-### Available Prompt Types
-
-- `call_transfer_initial_prompt`: The initial prompt the bot uses when greeting a customer
-- `call_transfer_prompt`: Instructions for the bot when summarizing the conversation for an operator
-- `call_transfer_finished_prompt`: Instructions for when the operator leaves the call
-- `voicemail_detection_prompt`: Instructions for detecting whether a call connected to voicemail
-- `voicemail_prompt`: The message to leave when voicemail is detected
-- `human_conversation_prompt`: Instructions for conversation when a human is detected
-
-### Customization Example
-
-```shell
-curl -X POST "http://localhost:7860/start" \
- -H "Content-Type: application/json" \
- -d '{
- "config": {
- "prompts": [
- {
- "name": "voicemail_prompt",
- "text": "Hello, this is ACME Corporation calling. Please call us back at 555-123-4567 regarding your recent order. Thank you!"
- }
- ],
- "dialout_settings": [{
- "phoneNumber": "+12345678910"
- }],
- "voicemail_detection": {
- "testInPrebuilt": false
- }
- }
- }'
-```
-
-This example would use all default prompts except for the voicemail message, which would be replaced with your custom message.
-
-### Template Variables
-
-Some prompts support template variables that are automatically replaced:
-
-- `{customer_name}`: Will be replaced with the customer's name if available
+All examples include default prompts that work well for standard use cases.

+# Daily PSTN Advanced Voicemail Detection Bot
+
+This project demonstrates how to create a voice bot that uses Dailys PSTN capabilities to make calls to phone numbers, and if the bot hits a voicemail system, to have the bot also leave a message. In this example, we have two pipelines. The voicemail detection pipeline uses Gemini Flash Lite, a fast and cheap LLM that works well for voicemail detection. The second pipeline uses Gemini Flash, a more advanced LLM model ideal for conversations.
+
+## How it works
+
+1. The server file receives a curl request with the phone number to dial out to
+2. The server creates a Daily room with SIP capabilities
+3. The server starts the bot process with the room details
+4. When the bot has joined, it starts the dial-out process and rings the number provided in the curl request
+5. When the phone is answered, the bot detects for certain key phrases
+6. Gemini Flash Lite works best when given small, concise prompts. When a voicemail machine is detected, we switch to a new prompt focused on the message that must be left
+7. Once the bot has left the message, it then ends the call
+8. If the bot detects there's a human on the phone, the bot runs a function call and switches to the human conversation pipeline. We give the new LLM a prompt and tell the LLM to speak.
+
+## Prerequisites
+
+- A Daily account with an API key, and a phone number purchased through Daily
+- A US phone number to ring
+- dial-out must be enabled on your domain. Find out more by reading this [document and filling in the form](https://docs.daily.co/guides/products/dial-in-dial-out#main)
+- Google API key for the bot's intelligence
+- Cartesia API key for text-to-speech
+
+## Setup
+
+1. Create a virtual environment and install dependencies
+
+```bash
+python -m venv venv
+source venv/bin/activate # On Windows: venv\Scripts\activate
+pip install -r requirements.txt
+```
+
+2. Set up environment variables
+
+Copy the example file and fill in your API keys:
+
+```bash
+cp .env.example .env
+# Edit .env with your API keys
+```
+
+3. Buy a phone number
+
+Instructions on how to do that can be found at this [docs link:](https://docs.daily.co/reference/rest-api/phone-numbers/buy-phone-number)
+
+4. Request dial-out enablement
+
+For compliance reasons, to enable dial-out for your Daily account, you must request enablement via the form. You can find out more about dial-out, and the form at the [link here:](https://docs.daily.co/guides/products/dial-in-dial-out#main)
+
+## Running the Server
+
+Start the webhook server:
+
+```bash
+python server.py
+```
+
+## Testing
+
+With server.py running, send the following curl command from your terminal:
+
+```bash
+curl -X POST "http://127.0.0.1:7860/start" \
+ -H "Content-Type: application/json" \
+ -d '{
+ "dialout_settings": {
+ "phone_number": "+12345678910"
+ }
+ }'
+```
+
+The server should make a room. The bot will join the room and then ring the number provided. Answer the call to speak with the bot.
+
+- You can pretend to be a voicemail machine by saying something like "Please leave a message after the beep... beeeeep".
+- You should observe the bot detects the voicemail machine and leaves a message before terminating the call
+- You can also say something like "Hello?", and the bot will notice you're likely a human and begin having a conversation with you
+
+## Customizing the Bot
+
+You can customize the bot's behavior by modifying the system prompt in `bot.py`.
+
+## Multiple SIP Endpoints
+
+For PSTN calls, you only need one SIP endpoint.
+
+## Daily dial-out configuration
+
+The bot configures the Daily rooms with dial-out capabilities using these settings. Note: You also need dial-out to be enabled on the domain, as mentioned earlier on in the README.
+
+```python
+properties = DailyRoomProperties(
+ sip=sip_params,
+ enable_dialout=True, # Needed for outbound calls if you expand the bot
+ enable_chat=False, # No need for chat in a voice bot
+ start_video_off=True, # Voice only
+)
+```
+
+## Troubleshooting
+
+### I get an error about dial-out not being enabled
+
+- Check that your room has `enable_dialout=True` set
+- Check that your meeting token is an owner token (The bot does this for you automatically)
+- Check that you have purchased a phone number to ring from
+- Check that the phone number you are trying to ring is correct, and is a US or Canadian number.
+
+### The bot doesn't detect my voicemail
+
+- The bot should be smart enough to detect variations of certain patterns,
+- If your voicemail machine doesn't follow the example patterns, add the pattern to the LLM prompt
+
+### Call connects but no bot is heard
+
+- Ensure your Daily API key is correct and has SIP capabilities
+- Verify that the Cartesia API key and voice ID are correct
+
+### Bot starts but disconnects immediately
+
+- Check the Daily logs for any error messages
+- Ensure your server has stable internet connectivity

+# Daily PSTN call transfer
+
+A basic example of how to create a bot that handles the initial customer interaction and then transfers to a human operator when needed
+
+## Architecture Overview
+
+These examples use the following components:
+
+- 🔁 **Transport**: Daily WebRTC
+- 💬 **Speech-to-Text**: Deepgram via Daily transport
+- 🤖 **LLMs**: Each example uses a specific LLM (OpenAI GPT-4o or Google Gemini)
+- 🔉 **Text-to-Speech**: Cartesia
+
+## Prerequisites
+
+- A Daily account with an API key
+- An OpenAI API key for the bot's intelligence
+- A Cartesia API key for text-to-speech
+- One phone to dial-in from and another phone to receive calls when escalating to a manager
+
+## Setup
+
+1. Create a virtual environment and install dependencies
+
+```bash
+python -m venv venv
+source venv/bin/activate # On Windows: venv\Scripts\activate
+pip install -r requirements.txt
+```
+
+2. Set up environment variables
+
+Copy the example file and fill in your API keys:
+
+```bash
+cp .env.example .env
+# Edit .env with your API keys
+```
+
+- Note, please specify an OPERATOR_NUMBER so that the bot can ring a number when escalating to a manager
+
+3. Buy a phone number
+
+Instructions on how to do that can be found at this [docs link:](https://docs.daily.co/reference/rest-api/phone-numbers/buy-phone-number).
+
+4. Set up the dial-in config
+
+Instructions on how to do that can be found at this [docs link:](https://docs.daily.co/reference/rest-api/domainDialinConfig)
+
+5. For local testing, use ngrok to expose your local server
+
+```bash
+ngrok http 7860
+# Then use the provided URL (e.g., https://abc123.ngrok.io/start) in Twilio
+```
+
+## Running the Server
+
+Start the webhook server:
+
+```bash
+python server.py
+```
+
+## Testing
+
+Call the purchased phone number. The system should answer the call, put you on hold briefly, then connect you with the bot.
+Have a short conversation with the bot, and then request to speak with a manager. The bot should then ring the manager. On your second phone, answer the call.
+
+The bot will then summarise the conversation so far, and then silently listen to the conversation. You can now speak with the manager on the other phone.
+
+When the manager hangs up the call, the bot will start speaking again. You can then ask the bot about the conversation with the manager, and it will have the context of the conversation.
+
+## Customizing the Bot
+
+You can customize the bot's behavior by modifying the system prompt in `bot.py`.
+
+## Multiple SIP Endpoints
+
+For PSTN calls, you only need one SIP endpoint.
+
+## Daily SIP Configuration
+
+The bot configures Daily rooms with SIP capabilities using these settings:
+
+```python
+sip_params = DailyRoomSipParams(
+ display_name="phone-user", # This will show up in the Daily UI; optional display the dialer's number
+ video=False, # Audio-only call
+ sip_mode="dial-in", # For receiving calls (vs. dial-out)
+ num_endpoints=1, # Number of SIP endpoints to create
+)
+
+properties = DailyRoomProperties(
+ sip=sip_params,
+ enable_dialout=True, # Needed for outbound calls if you expand the bot
+ enable_chat=False, # No need for chat in a voice bot
+ start_video_off=True, # Voice only
+)
+```
+
+## Troubleshooting
+
+### Call is not being answered
+
+- Check that your dial-in config is correctly configured to point towards your ngrok server and correct endpoint
+- Make sure the server.py file is running
+- Make sure ngrok is correctly setup and pointing to the correct port
+
+### The bot does not escalate to the manager
+
+- Check that your room has `enable_dialout=True` set
+- Check that your meeting token is an owner token (The bot does this for you automatically)
+- Check that the phone number you are trying to ring is correct, and is a US or Canadian number.
+
+### Call connects but no bot is heard
+
+- Ensure your Daily API key is correct and has SIP capabilities
+- Verify that the Cartesia API key and voice ID are correct
+
+### Bot starts but disconnects immediately
+
+- Check the Daily logs for any error messages
+- Ensure your server has stable internet connectivity

+
+# Daily PSTN dial-in simple chatbot
+
+This project demonstrates how to create a voice bot that can receive phone calls via Dailys PSTN capabilities to enable voice conversations.
+
+## How It Works
+
+1. Daily receives an incoming call to your phone number.
+2. Daily calls your webhook server (`/start` endpoint).
+3. The server creates a Daily room with dial-in capabilities
+4. The server starts the bot process with the room details
+5. The caller is put on hold with music
+6. The bot joins the Daily room and signals readiness
+7. Daily forwards the call to the Daily room
+8. The caller and the bot are connected, and the bot handles the conversation
+
+## Prerequisites
+
+- A Daily account with an API key
+- An OpenAI API key for the bot's intelligence
+- A Cartesia API key for text-to-speech
+
+## Setup
+
+1. Create a virtual environment and install dependencies
+
+```bash
+python -m venv venv
+source venv/bin/activate # On Windows: venv\Scripts\activate
+pip install -r requirements.txt
+```
+
+2. Set up environment variables
+
+Copy the example file and fill in your API keys:
+
+```bash
+cp .env.example .env
+# Edit .env with your API keys
+```
+
+3. Buy a phone number
+
+Instructions on how to do that can be found at this [docs link:](https://docs.daily.co/reference/rest-api/phone-numbers/buy-phone-number)
+
+4. Set up the dial-in config
+
+Instructions on how to do that can be found at this [docs link:](https://docs.daily.co/reference/rest-api/domainDialinConfig)
+
+5. For local testing, use ngrok to expose your local server
+
+```bash
+ngrok http 7860
+# Then use the provided URL (e.g., https://abc123.ngrok.io/start) in Twilio
+```
+
+## Running the Server
+
+Start the webhook server:
+
+```bash
+python server.py
+```
+
+## Testing
+
+Call the purchased phone number. The system should answer the call, put you on hold briefly, then connect you with the bot.
+
+## Customizing the Bot
+
+You can customize the bot's behavior by modifying the system prompt in `bot.py`.
+
+## Multiple SIP Endpoints
+
+For PSTN calls, you only need one SIP endpoint.
+
+## Daily SIP Configuration
+
+The bot configures Daily rooms with SIP capabilities using these settings:
+
+```python
+sip_params = DailyRoomSipParams(
+ display_name="phone-user", # This will show up in the Daily UI; optional display the dialer's number
+ video=False, # Audio-only call
+ sip_mode="dial-in", # For receiving calls (vs. dial-out)
+ num_endpoints=1, # Number of SIP endpoints to create
+)
+```
+
+## Troubleshooting
+
+### Call is not being answered
+
+- Check that your dial-in config is correctly configured to point towards your ngrok server and correct endpoint
+- Make sure the server.py file is running
+- Make sure ngrok is correctly setup and pointing to the correct port
+
+### Call connects but no bot is heard
+
+- Ensure your Daily API key is correct and has SIP capabilities
+- Verify that the Cartesia API key and voice ID are correct
+
+### Bot starts but disconnects immediately
+
+- Check the Daily logs for any error messages
+- Ensure your server has stable internet connectivity

+# Daily PSTN dial-out simple chatbot
+
+This project demonstrates how to create a voice bot that uses Dailys PSTN capabilities to make calls to phone numbers.
+
+## How it works
+
+1. The server file receives a curl request with the phone number to dial out to
+2. The server creates a Daily room with SIP capabilities
+3. The server starts the bot process with the room details
+4. When the bot has joined, it starts the dial-out process and rings the number provided in the curl request
+5. The user then answers the phone and the user is brought into the call
+6. The end user and bot are connected, and the bot handles the conversation
+
+## Prerequisites
+
+- A Daily account with an API key, and a phone number purchased through Daily
+- A US phone number to ring
+- dial-out must be enabled on your domain. Find out more by reading this [document and filling in the form](https://docs.daily.co/guides/products/dial-in-dial-out#main)
+- OpenAI API key for the bot's intelligence
+- Cartesia API key for text-to-speech
+
+## Setup
+
+1. Create a virtual environment and install dependencies
+
+```bash
+python -m venv venv
+source venv/bin/activate # On Windows: venv\Scripts\activate
+pip install -r requirements.txt
+```
+
+2. Set up environment variables
+
+Copy the example file and fill in your API keys:
+
+```bash
+cp .env.example .env
+# Edit .env with your API keys
+```
+
+3. Buy a phone number
+
+Instructions on how to do that can be found at this [docs link:](https://docs.daily.co/reference/rest-api/phone-numbers/buy-phone-number)
+
+4. Request dial-out enablement
+
+For compliance reasons, to enable dial-out for your Daily account, you must request enablement via the form. You can find out more about dial-out, and the form at the [link here:](https://docs.daily.co/guides/products/dial-in-dial-out#main)
+
+## Running the Server
+
+Start the webhook server:
+
+```bash
+python server.py
+```
+
+## Testing
+
+With server.py running, send the following curl command from your terminal:
+
+```bash
+curl -X POST "http://127.0.0.1:7860/start" \
+ -H "Content-Type: application/json" \
+ -d '{
+ "dialout_settings": {
+ "phone_number": "+12345678910"
+ }
+ }'
+```
+
+The server should make a room. The bot will join the room and then ring the number provided. Answer the call to speak with the bot.
+
+## Customizing the Bot
+
+You can customize the bot's behavior by modifying the system prompt in `bot.py`.
+
+## Multiple SIP Endpoints
+
+For PSTN calls, you only need one SIP endpoint.
+
+## Daily dial-out configuration
+
+The bot configures the Daily rooms with dial-out capabilities using these settings. Note: You also need dial-out to be enabled on the domain, as mentioned earlier on in the README.
+
+```python
+properties = DailyRoomProperties(
+ sip=sip_params,
+ enable_dialout=True, # Needed for outbound calls if you expand the bot
+ enable_chat=False, # No need for chat in a voice bot
+ start_video_off=True, # Voice only
+)
+```
+
+## Troubleshooting
+
+### I get an error about dial-out not being enabled
+
+- Check that your room has `enable_dialout=True` set
+- Check that your meeting token is an owner token (The bot does this for you automatically)
+- Check that you have purchased a phone number to ring from
+- Check that the phone number you are trying to ring is correct, and is a US or Canadian number.
+
+### Call connects but no bot is heard
+
+- Ensure your Daily API key is correct and has SIP capabilities
+- Verify that the Cartesia API key and voice ID are correct
+
+### Bot starts but disconnects immediately
+
+- Check the Daily logs for any error messages
+- Ensure your server has stable internet connectivity

+# Daily PSTN Simple Voicemail Detection Bot
+
+This project demonstrates how to create a voice bot that uses Dailys PSTN capabilities to make calls to phone numbers, and if the bot hits a voicemail system, to have the bot also leave a message.
+
+## How it works
+
+1. The server file receives a curl request with the phone number to dial out to
+2. The server creates a Daily room with SIP capabilities
+3. The server starts the bot process with the room details
+4. When the bot has joined, it starts the dial-out process and rings the number provided in the curl request
+5. When the phone is answered, the bot detects for certain key phrases
+6. If the bot detects those key phrases, it leaves a messages and then ends the call
+7. If the bot detects there's a human on the phone, it behaves like a regular bot
+
+## Prerequisites
+
+- A Daily account with an API key, and a phone number purchased through Daily
+- A US phone number to ring
+- dial-out must be enabled on your domain. Find out more by reading this [document and filling in the form](https://docs.daily.co/guides/products/dial-in-dial-out#main)
+- Google API key for the bot's intelligence
+- Cartesia API key for text-to-speech
+
+## Setup
+
+1. Create a virtual environment and install dependencies
+
+```bash
+python -m venv venv
+source venv/bin/activate # On Windows: venv\Scripts\activate
+pip install -r requirements.txt
+```
+
+2. Set up environment variables
+
+Copy the example file and fill in your API keys:
+
+```bash
+cp .env.example .env
+# Edit .env with your API keys
+```
+
+3. Buy a phone number
+
+Instructions on how to do that can be found at this [docs link:](https://docs.daily.co/reference/rest-api/phone-numbers/buy-phone-number)
+
+4. Request dial-out enablement
+
+For compliance reasons, to enable dial-out for your Daily account, you must request enablement via the form. You can find out more about dial-out, and the form at the [link here:](https://docs.daily.co/guides/products/dial-in-dial-out#main)
+
+## Running the Server
+
+Start the webhook server:
+
+```bash
+python server.py
+```
+
+## Testing
+
+With server.py running, send the following curl command from your terminal:
+
+```bash
+curl -X POST "http://127.0.0.1:7860/start" \
+ -H "Content-Type: application/json" \
+ -d '{
+ "dialout_settings": {
+ "phone_number": "+12345678910"
+ }
+ }'
+```
+
+The server should make a room. The bot will join the room and then ring the number provided. Answer the call to speak with the bot.
+
+- You can pretend to be a voicemail machine by saying something like "Please leave a message after the beep... beeeeep".
+- You should observe the bot detects the voicemail machine and leaves a message before terminating the call
+- You can also say something like "Hello?", and the bot will notice you're likely a human and begin having a conversation with you
+
+## Customizing the Bot
+
+You can customize the bot's behavior by modifying the system prompt in `bot.py`.
+
+## Multiple SIP Endpoints
+
+For PSTN calls, you only need one SIP endpoint.
+
+## Daily dial-out configuration
+
+The bot configures the Daily rooms with dial-out capabilities using these settings. Note: You also need dial-out to be enabled on the domain, as mentioned earlier on in the README.
+
+```python
+properties = DailyRoomProperties(
+ sip=sip_params,
+ enable_dialout=True, # Needed for outbound calls if you expand the bot
+ enable_chat=False, # No need for chat in a voice bot
+ start_video_off=True, # Voice only
+)
+```
+
+## Troubleshooting
+
+### I get an error about dial-out not being enabled
+
+- Check that your room has `enable_dialout=True` set
+- Check that your meeting token is an owner token (The bot does this for you automatically)
+- Check that you have purchased a phone number to ring from
+- Check that the phone number you are trying to ring is correct, and is a US or Canadian number.
+
+### The bot doesn't detect my voicemail
+
+- The bot should be smart enough to detect variations of certain patterns,
+- If your voicemail machine doesn't follow the example patterns, add the pattern to the LLM prompt
+
+### Call connects but no bot is heard
+
+- Ensure your Daily API key is correct and has SIP capabilities
+- Verify that the Cartesia API key and voice ID are correct
+
+### Bot starts but disconnects immediately
+
+- Check the Daily logs for any error messages
+- Ensure your server has stable internet connectivity

+
+ **Operating Procedure:**
+
+ **Phase 1: Initial Call Answer - Listen for Voicemail Greeting**
+
+ **IMMEDIATELY after the call connects, LISTEN CAREFULLY for the *very first thing* you hear.**
+
+ If you hear any of these phrases (or very similar ones):
+ - "Please leave a message after the beep"
+ - "No one is available to take your call"
+ - "Record your message after the tone"
+ - "You have reached voicemail for..."
+ - "You have reached [phone number]"
+ - "[phone number] is unavailable"
+ - "The person you are trying to reach..."
+ - "The number you have dialed..."
+ - "Your call has been forwarded to an automated voice messaging system"
+
+ **If you HEAR one of these sentences (or a very similar greeting) as the *initial response* to the call, IMMEDIATELY assume it is voicemail and proceed to Phase 2.**
+
+ **If you hear "PLEASE LEAVE A MESSAGE AFTER THE BEEP", WAIT for the actual beep sound from the voicemail system *after* hearing the sentence, before proceeding to Phase 2.**
+
+ **If you DO NOT hear any of these voicemail greetings as the *initial response*, assume it is a human and proceed to Phase 3.**
+
+
+ **Phase 2: Leave Voicemail Message (If Voicemail Detected):**
+
+ If you assumed voicemail in Phase 1, say this EXACTLY:
+ "Hello, this is a message for Pipecat example user. This is Chatbot. Please call back on 123-456-7891. Thank you."
+
+ **Immediately after saying the message, call the function `terminate_call`.**
+ **DO NOT SAY ANYTHING ELSE. SILENCE IS REQUIRED AFTER `terminate_call`.**
+
+
+ **Phase 3: Human Interaction (If No Voicemail Greeting Detected in Phase 1):**
+
+ If you did not detect a voicemail greeting in Phase 1 and a human answers, say:
+ "Oh, hello! I'm a friendly chatbot. Is there anything I can help you with?"
+
+ Keep your responses **short and helpful.**
+
+ When the person indicates they're done with the conversation by saying something like:
+ - "Goodbye"
+ - "That's all"
+ - "I'm done"
+ - "Thank you, that's all I needed"
+
+
+ THEN say: "Thank you for chatting. Goodbye!" and call the terminate_call function.
+
+ **Then, immediately call the function `terminate_call`.**
+
+
+ **VERY IMPORTANT RULES - DO NOT DO THESE THINGS:**
+
+ * **DO NOT SAY "Please leave a message after the beep."**
+ * **DO NOT SAY "No one is available to take your call."**
+ * **DO NOT SAY "Record your message after the tone."**
+ * **DO NOT SAY ANY voicemail greeting yourself.**
+ * **Only check for voicemail greetings in Phase 1, *immediately after the call connects*.**
+ * **After voicemail or human interaction, ALWAYS call `terminate_call` immediately.**
+ * **Do not speak after calling `terminate_call`.**
+ * Your speech will be audio, so use simple language without special characters.

+
+# Daily + Twilio SIP dial-out Voice Bot
+
+This project demonstrates how to create a voice bot that can make phone calls via Twilio and use Daily's SIP capabilities to enable voice conversations.
+
+## How it works
+
+1. The server file receives a curl request with the SIP uri to dial out to
+2. The server creates a Daily room with SIP capabilities
+3. The server starts the bot process with the room details
+4. When the bot has joined, it starts the dial-out process and dials out to the SIP uri provided in the curl request
+5. Twilio receives the request, and the provided TWIML processes the SIP uri
+6. Twilio then rings the number found within the SIP uri
+7. When the user answers the phone, the user is brought into the call
+8. The end user and the bot are connected, and the bot handles the conversation
+
+## Prerequisites
+
+- A Daily account with an API key
+- A Twilio account with a phone number that supports voice and a correctly configured SIP domain
+- OpenAI API key for the bot's intelligence
+- Cartesia API key for text-to-speech
+
+## Setup
+
+1. Create a virtual environment and install dependencies
+
+```bash
+python -m venv venv
+source venv/bin/activate # On Windows: venv\Scripts\activate
+pip install -r requirements.txt
+```
+
+2. Set up environment variables
+
+Copy the example file and fill in your API keys:
+
+```bash
+cp .env.example .env
+# Edit .env with your API keys
+```
+
+3. Create a TwiML Bin
+
+Visit this link to create your [TwiML Bin](https://www.twilio.com/docs/serverless/twiml-bins)
+
+- Login to the account that has your purchased Twilio phone number
+- Press the plus button on the TwiML Bin dashboard to write a new TwiML that Twilio will host for you
+- Give it a friendly name. For example "daily sip uri twiml bin"
+- For the TWIML code, use something like:
+
+```xml
+
+
+ {{#e164}}{{To}}{{/e164}}
+
+```
+
+- callerId must be a valid number that you own on [Twilio](https://console.twilio.com/us1/develop/phone-numbers/manage/incoming)
+- Save the file. We will use this when creating the SIP domain
+
+4. Create and configure a programmable SIP domain
+
+- Visit this link to [create a new SIP domain:](https://console.twilio.com/us1/develop/voice/manage/sip-domains?frameUrl=%2Fconsole%2Fvoice%2Fsip%2Fendpoints%3Fx-target-region%3Dus1)
+- Press the plus button to create a new SIP domain
+- Give the SIP domain a friendly name. For example "Daily SIP domain"
+- Specify a SIP URI, for example "daily.sip.twilio.com"
+- Under "Voice Authentication", press the plus button next to IP Access Control Lists. We are going to white list the entire IP spectrum
+- Give it a friendly name such as "first half"
+- For CIDR Network Address specify 0.0.0.0 and for the subnet specify 1
+- Again, specify "first half" for the friendly name and click "Create ACL"
+- Now let's do the same again and add another IP Access Control List by pressing the plus button
+- Give it a friendly name such as "second half".
+- For the CIDR Network Address specify 128.0.0.0 and for the subnet specify 1
+- Lastly, specify the friendly name "second half" again
+- Make sure both IP Access control list appears selected in the dropdown
+- Under "Call Control Configuration", specify the following:
+- Configure with: Webhooks, TwiML Bins, Functions, Studio, Proxy
+- A call comes in: TwiML Bin > Select the name of the TwiML bin you made earlier
+- Leave everything else blank and scroll to the bottom of the page. Click save
+
+## Running the Server
+
+Start the webhook server:
+
+```bash
+python server.py
+```
+
+## Testing
+
+With server.py running, send the following curl command from your terminal:
+
+```bash
+curl -X POST "http://127.0.0.1:7860/start" \
+ -H "Content-Type: application/json" \
+ -d '{
+ "dialout_settings": {
+ "sip_uri": "sip:+1234567891@daily.sip.twilio.com"
+ }
+ }'
+```
+
+- Replace the phone number (Starting with +1) with the phone number you want to ring
+- Replace daily with the SIP domain you configured previously
+
+The server should make a room. The bot will join the room and then dial out to the SIP URI provided. Answer the call to speak with the bot.
+
+## Customizing the Bot
+
+You can customize the bot's behavior by modifying the system prompt in `bot.py`.
+
+## Handling Multiple SIP Endpoints
+
+Note that normally calls only require a single SIP endpoint. If you are planning to forward the call to a different number, you will need to set up 2 SIP endpoints: one for the initial call and one for the forwarded call.
+
+## Daily dial-out configuration
+
+The bot configures the Daily rooms with dial-out capabilities using these settings. Note: You also need dial-out to be enabled on the domain, as mentioned earlier on in the README.
+
+```python
+properties = DailyRoomProperties(
+ sip=sip_params,
+ enable_dialout=True, # Needed for outbound calls if you expand the bot
+ enable_chat=False, # No need for chat in a voice bot
+ start_video_off=True, # Voice only
+)
+```
+
+## Troubleshooting
+
+### I get an error about dial-out not being enabled
+
+- Check that your room has `enable_dialout=True` set
+- Check that your meeting token is an owner token (The bot does this for you automatically)
+- Check that the SIP URI is correct
+- Check that the phone number you are trying to ring is correct
+
+### I'm stuck setting up my Twilio account
+
+- You can reference this [Notion doc](https://dailyco.notion.site/PUBLIC-Doc-Integration-Twilio-PSTN-Daily-s-SIP-Dialout-1cfdaed630f5458d9d4fc0e3f29ec559) to find more information on how to set up Twilio, as well as use webhooks instead of TwiML Bins
+
+### Call connects but no bot is heard
+
+- Ensure your Daily API key is correct and has SIP capabilities
+- Verify that the Cartesia API key and voice ID are correct
+
+### Bot starts but disconnects immediately
+
+- Check the Daily logs for any error messages
+- Ensure your server has stable internet connectivity
