CHANGELOG.md

@@ -9,6 +9,302 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 
 ### Added
 
+- Added `RTVIObserverParams` which allows you to configure what RTVI messages
+  are sent to the clients.
+
+- Added a `context_window_compression` InputParam to
+  `GeminiMultimodalLiveLLMService` which allows you to enable a sliding context
+  window for the session as well as set the token limit of the sliding window.
+
+- Updated `SmallWebRTCConnection` to support `ice_servers` with credentials.
+
+- Added `VADUserStartedSpeakingFrame` and `VADUserStoppedSpeakingFrame`,
+  indicating when the VAD detected the user to start and stop speaking. These
+  events are helpful when using smart turn detection, as the user's stop time
+  can differ from when their turn ends (signified by UserStoppedSpeakingFrame).
+
+- Added `TranslationFrame`, a new frame type that contains a translated
+  transcription.
+
+- Added `TransportParams.audio_in_passthrough`. If set (the default), incoming
+  audio will be pushed downstream.
+
+- Added `MCPClient`; a way to connect to MCP servers and use the MCP servers'
+  tools.
+
+- Added `Mem0 OSS`, along with Mem0 cloud support now the OSS version is also
+  available.
+
+### Changed
+
+- The `STTMuteFilter` now mutes `InterimTranscriptionFrame` and
+  `TranscriptionFrame` which allows the `STTMuteFilter` to be used in
+  conjunction with transports that generate transcripts, e.g. `DailyTransport`.
+
+- Function calls now receive a single parameter `FunctionCallParams` instead of
+  `(function_name, tool_call_id, args, llm, context, result_callback)` which is
+  now deprecated.
+
+- Changed the user aggregator timeout for late transcriptions from 1.0s to 0.5s
+  (`LLMUserAggregatorParams.aggregation_timeout`). Sometimes, the STT services
+  might give us more than one transcription which could come after the user
+  stopped speaking. We still want to include these additional transcriptions
+  with the first one because it's part of the user turn. This is what this
+  timeout is helpful with.
+
+- Short utterances not detected by VAD while the bot is speaking are now
+  ignored. This reduces the amount of bot interruptions significantly providing
+  a more natural conversation experience.
+
+- Updated `GladiaSTTService` to output a `TranslationFrame` when specifying a
+  `translation` and `translation_config`.
+
+- STT services now passthrough audio frames by default. This allows you to add
+  audio recording without worrying about what's wrong in your pipeline when it
+  doesn't work the first time.
+
+- Input transports now always push audio downstream unless disabled with
+  `TransportParams.audio_in_passthrough`. After many Pipecat releases, we
+  realized this is the common use case. There are use cases where the input
+  transport already provides STT and you also don't want recordings, in which
+  case there's no need to push audio to the rest of the pipeline, but this is
+  not a very common case.
+
+### Deprecated
+
+- Function calls with parameters
+  `(function_name, tool_call_id, args, llm, context, result_callback)` are
+  deprectated, use a single `FunctionCallParams` parameter instead.
+
+- `TransportParams.camera_*` parameters are now deprecated, use
+  `TransportParams.video_*` instead.
+
+- `TransportParams.vad_enabled` parameter is now deprecated, use
+  `TransportParams.audio_in_enabled` and `TransportParams.vad_analyzer` instead.
+
+- `TransportParams.vad_audio_passthrough` parameter is now deprecated, use
+  `TransportParams.audio_in_passthrough` instead.
+
+### Fixed
+
+- Fixed an issue with `GeminiMultimodalLiveLLMService` where the context
+  contained tokens instead of words.
+
+- Fixed an issue with HTTP Smart Turn handling, where the service returns a 500
+  error. Previously, this would cause an unhandled exception. Now, a 500 error
+  is treated as an incomplete response.
+
+- Fixed a TTS services issue that could cause assistant output not to be
+  aggregated to the context when also using `TTSSpeakFrame`s.
+
+- Fixed an issue where the `SmartTurnMetricsData` was reporting 0ms for
+  inference and processing time when using the `FalSmartTurnAnalyzer`.
+
+### Other
+
+- Added 04 foundational examples for client/server transports. Also, renamed
+  `29-livekit-audio-chat.py` to `04b-transports-livekit.py`.
+
+- Added foundational example `13c-gladia-translation.py` showing how to use
+  `TranscriptionFrame` and `TranslationFrame`.
+
+## [0.0.65] - 2025-04-23 "Sant Jordi's release" 🌹📕
+
+https://en.wikipedia.org/wiki/Saint_George%27s_Day_in_Catalonia
+
+### Added
+
+- Added automatic hangup logic to the Telnyx serializer. This feature hangs up
+  the Telnyx call when an `EndFrame` or `CancelFrame` is received. It is
+  enabled by default and is configurable via the `auto_hang_up` `InputParam`.
+
+- Added a keepalive task to `GladiaSTTService` to prevent the websocket from
+  disconnecting after 30 seconds of no audio input.
+
+### Changed
+
+- The `InputParams` for `ElevenLabsTTSService` and `ElevenLabsHttpTTSService`
+  no longer require that `stability` and `similarity_boost` be set. You can
+  individually set each param.
+
+- In `TwilioFrameSerializer`, `call_sid` is Optional so as to avoid a breaking
+  changed. `call_sid` is required to automatically hang up.
+
+### Fixed
+
+- Fixed an issue where `TwilioFrameSerializer` would send two hang up commands:
+  one for the `EndFrame` and one for the `CancelFrame`.
+
+## [0.0.64] - 2025-04-22
+
+### Added
+
+- Added automatic hangup logic to the Twilio serializer. This feature hangs up
+  the Twilio call when an `EndFrame` or `CancelFrame` is received. It is
+  enabled by default and is configurable via the `auto_hang_up` `InputParam`.
+
+- Added `SmartTurnMetricsData`, which contains end-of-turn prediction metrics,
+  to the `MetricsFrame`. Using `MetricsFrame`, you can now retrieve prediction
+  confidence scores and processing time metrics from the smart turn analyzers.
+
+- Added support for Application Default Credentials in Google services,
+  `GoogleSTTService`, `GoogleTTSService`, and `GoogleVertexLLMService`.
+
+- Added support for Smart Turn Detection via the `turn_analyzer` transport
+  parameter. You can now choose between `HttpSmartTurnAnalyzer()` or
+  `FalSmartTurnAnalyzer()` for remote inference or
+  `LocalCoreMLSmartTurnAnalyzer()` for on-device inference using Core ML.
+
+- `DeepgramTTSService` accepts `base_url` argument again, allowing you to
+  connect to an on-prem service.
+
+- Added `LLMUserAggregatorParams` and `LLMAssistantAggregatorParams` which allow
+  you to control aggregator settings. You can now pass these arguments when
+  creating aggregator pairs with `create_context_aggregator()`.
+
+- Added `previous_text` context support to ElevenLabsHttpTTSService, improving
+  speech consistency across sentences within an LLM response.
+
+- Added word/timestamp pairs to `ElevenLabsHttpTTSService`.
+
+- It is now possible to disable `SoundfileMixer` when created. You can then use
+  `MixerEnableFrame` to dynamically enable it when necessary.
+
+- Added `on_client_connected` and `on_client_disconnected` event handlers to
+  the `DailyTransport` class. These handlers map to the same underlying Daily
+  events as `on_participant_joined` and `on_participant_left`, respectively.
+  This makes it easier to write a single bot pipeline that can also use other
+  transports like `SmallWebRTCTransport` and `FastAPIWebsocketTransport`.
+
+### Changed
+
+- `GrokLLMService` now uses `grok-3-beta` as its default model.
+
+- Daily's REST helpers now include an `eject_at_token_exp` param, which ejects
+  the user when their token expires. This new parameter defaults to False.
+  Also, the default value for `enable_prejoin_ui` changed to False and
+  `eject_at_room_exp` changed to False.
+
+- `OpenAILLMService` and `OpenPipeLLMService` now use `gpt-4.1` as their
+  default model.
+
+- `SoundfileMixer` constructor arguments need to be keywords.
+
+### Deprecated
+
+- `DeepgramSTTService` parameter `url` is now deprecated, use `base_url`
+  instead.
+
+### Removed
+
+- Parameters `user_kwargs` and `assistant_kwargs` when creating a context
+  aggregator pair using `create_context_aggregator()` have been removed. Use
+  `user_params` and `assistant_params` instead.
+
+### Fixed
+
+- Fixed an issue that would cause TTS websocket-based services to not cleanup
+  resources properly when disconnecting.
+
+- Fixed a `TavusVideoService` issue that was causing audio choppiness.
+
+- Fixed an issue in `SmallWebRTCTransport` where an error was thrown if the
+  client did not create a video transceiver.
+
+- Fixed an issue where LLM input parameters were not working and applied
+  correctly in `GoogleVertexLLMService`, causing unexpected behavior during
+  inference.
+
+### Other
+
+- Updated the `twilio-chatbot` example to use the auto-hangup feature.
+
+## [0.0.63] - 2025-04-11
+
+### Added
+
+- Added media resolution control to `GeminiMultimodalLiveLLMService` with
+  `GeminiMediaResolution` enum, allowing configuration of token usage for
+  image processing (LOW: 64 tokens, MEDIUM: 256 tokens, HIGH: zoomed reframing
+  with 256 tokens).
+
+- Added Gemini's Voice Activity Detection (VAD) configuration to
+  `GeminiMultimodalLiveLLMService` with `GeminiVADParams`, allowing fine
+  control over speech detection sensitivity and timing, including:
+
+  - Start sensitivity (how quickly speech is detected)
+  - End sensitivity (how quickly turns end after pauses)
+  - Prefix padding (milliseconds of audio to keep before speech is detected)
+  - Silence duration (milliseconds of silence required to end a turn)
+
+- Added comprehensive language support to `GeminiMultimodalLiveLLMService`,
+  supporting over 30 languages via the `language` parameter, with proper
+  mapping between Pipecat's `Language` enum and Gemini's language codes.
+
+- Added support in `SmallWebRTCTransport` to detect when remote tracks are
+  muted.
+
+- Added support for image capture from a video stream to the
+  `SmallWebRTCTransport`.
+
+- Added a new iOS client option to the `SmallWebRTCTransport`
+  **video-transform** example.
+
+- Added new processors `ProducerProcessor` and `ConsumerProcessor`. The
+  producer processor processes frames from the pipeline and decides whether the
+  consumers should consume it or not. If so, the same frame that is received by
+  the producer is sent to the consumer. There can be multiple consumers per
+  producer. These processors can be useful to push frames from one part of a
+  pipeline to a different one (e.g. when using `ParallelPipeline`).
+
+- Improvements for the `SmallWebRTCTransport`:
+  - Wait until the pipeline is ready before triggering the `connected` event.
+  - Queue messages if the data channel is not ready.
+  - Update the aiortc dependency to fix an issue where the 'video/rtx' MIME
+    type was incorrectly handled as a codec retransmission.
+  - Avoid initial video delays.
+
+### Changed
+
+- In `GeminiMultimodalLiveLLMService`, removed the `transcribe_model_audio`
+  parameter in favor of Gemini Live's native output transcription support. Now
+  text transcriptions are produced directly by the model. No configuration is
+  required.
+
+- Updated `GeminiMultimodalLiveLLMService`’s default `model` to
+  `models/gemini-2.0-flash-live-001` and `base_url` to the `v1beta` websocket
+  URL.
+
+### Fixed
+
+- Updated `daily-python` to 0.17.0 to fix an issue that was preventing to run on
+  older platforms.
+
+- Fixed an issue where `CartesiaTTSService`'s spell feature would result in
+  the spelled word in the context appearing as "F,O,O,B,A,R" instead of
+  "FOOBAR".
+
+- Fixed an issue in the Azure TTS services where the language was being set
+  incorrectly.
+
+- Fixed `SmallWebRTCTransport` to support dynamic values for
+  `TransportParams.audio_out_10ms_chunks`. Previously, it only worked with 20ms
+  chunks.
+
+- Fixed an issue with `GeminiMultimodalLiveLLMService` where the assistant
+  context messages had no space between words.
+
+- Fixed an issue where `LLMAssistantContextAggregator` would prevent a
+  `BotStoppedSpeakingFrame` from moving through the pipeline.
+
+## [0.0.62] - 2025-04-01 "An April Fools' release"
+
+### Added

+- Added `TransportParams.audio_out_10ms_chunks` parameter to allow controlling

-## A simple voice agent running locally
+## 🛠️ Hacking on the framework itself
 
-Here is a very basic Pipecat bot that greets a user when they join a real-time session. We'll use [Daily](https://daily.co) for real-time media transport, and [Cartesia](https://cartesia.ai/) for text-to-speech.
+1. Set up a virtual environment before following these instructions. From the root of the repo:
 
-```python
-import asyncio
+   ```shell
+   python3 -m venv venv
+   source venv/bin/activate
+   ```
 
-from pipecat.frames.frames import TextFrame
-from pipecat.pipeline.pipeline import Pipeline
-from pipecat.pipeline.task import PipelineTask
-from pipecat.pipeline.runner import PipelineRunner
-from pipecat.services.cartesia import CartesiaTTSService
-from pipecat.transports.services.daily import DailyParams, DailyTransport
+2. Install the development dependencies:
 
-async def main():
-  # Use Daily as a real-time media transport (WebRTC)
-  transport = DailyTransport(
-    room_url=...,
-    token="", # leave empty. Note: token is _not_ your api key
-    bot_name="Bot Name",
-    params=DailyParams(audio_out_enabled=True))
+   ```shell
+   pip install -r dev-requirements.txt
+   ```
 
-  # Use Cartesia for Text-to-Speech
-  tts = CartesiaTTSService(
-    api_key=...,
-    voice_id=...
-  )
+3. Install the git pre-commit hooks (these help ensure your code follows project rules):
 
-  # Simple pipeline that will process text to speech and output the result
-  pipeline = Pipeline([tts, transport.output()])
+   ```shell
+   pre-commit install
+   ```
 
-  # Create Pipecat processor that can run one or more pipelines tasks
-  runner = PipelineRunner()
+4. Install the `pipecat-ai` package locally in editable mode:
 
-  # Assign the task callable to run the pipeline
-  task = PipelineTask(pipeline)
+   ```shell
+   pip install -e .
+   ```
 
-  # Register an event handler to play audio when a
-  # participant joins the transport WebRTC session
-  @transport.event_handler("on_first_participant_joined")
-  async def on_first_participant_joined(transport, participant):
-    participant_name = participant.get("info", {}).get("userName", "")
-    # Queue a TextFrame that will get spoken by the TTS service (Cartesia)
-    await task.queue_frame(TextFrame(f"Hello there, {participant_name}!"))
+   > The `-e` or `--editable` option allows you to modify the code without reinstalling.
 
-  # Register an event handler to exit the application when the user leaves.
-  @transport.event_handler("on_participant_left")
-  async def on_participant_left(transport, participant, reason):
-    await task.cancel()
+5. Include optional dependencies as needed. For example:
 
-  # Run the pipeline task
-  await runner.run(task)
+   ```shell
+   pip install -e ".[daily,deepgram,cartesia,openai,silero]"
+   ```
 
-if __name__ == "__main__":
-  asyncio.run(main())
-```
+6. (Optional) If you want to use this package from another directory:
 
-Run it with:
-
-```shell
-python app.py
-```
-
-Daily provides a prebuilt WebRTC user interface. While the app is running, you can visit at `https://<yourdomain>.daily.co/<room_url>` and listen to the bot say hello!
-
-## WebRTC for production use
-
-WebSockets are fine for server-to-server communication or for initial development. But for production use, you’ll need client-server audio to use a protocol designed for real-time media transport. (For an explanation of the difference between WebSockets and WebRTC, see [this post.](https://www.daily.co/blog/how-to-talk-to-an-llm-with-your-voice/#webrtc))
-
-One way to get up and running quickly with WebRTC is to sign up for a Daily developer account. Daily gives you SDKs and global infrastructure for audio (and video) routing. Every account gets 10,000 audio/video/transcription minutes free each month.
-
-Sign up [here](https://dashboard.daily.co/u/signup) and [create a room](https://docs.daily.co/reference/rest-api/rooms) in the developer Dashboard.

-## Hacking on the framework itself
-
-_Note: You may need to set up a virtual environment before following these instructions. From the root of the repo:_
-
-```shell
-python3 -m venv venv
-source venv/bin/activate
-```
-
-Install the development dependencies:
-
-```shell
-pip install -r dev-requirements.txt
-```
-
-Install the git pre-commit hooks (these help ensure your code follows project rules):
-
-```shell
-pre-commit install
-```
-
-Install the `pipecat-ai` package locally in editable mode:
-
-```shell
-pip install -e .
-```
-
-The `-e` or `--editable` option allows you to modify the code without reinstalling.
-
-To include optional dependencies, add them to the install command. For example:
-
-```shell
-pip install -e ".[daily,deepgram,cartesia,openai,silero]"     # Updated for the services you're using
-```
-
-If you want to use this package from another directory:
-
-```shell
-pip install "path_to_this_repo[option,...]"
-```
+   ```shell
+   pip install "path_to_this_repo[option,...]"
+   ```
 
 ### Running tests
 
+Install the test dependencies:
+
+```shell
+pip install -r test-requirements.txt
+```
+
 From the root directory, run:
 
 ```shell
 pytest
 ```

+# Handling PSTN/SIP Dial-in on Pipecat Cloud
+
+This repository contains two server implementations for handling
+the pinless dial-in workflow in Pipecat Cloud. This is the companion to the
+Pipecat Cloud [pstn_sip starter image](https://github.com/daily-co/pipecat-cloud-images/tree/main/pipecat-starters/pstn_sip).
+In addition you can use `/api/dial` to trigger dial-out, and
+eventually, call-transfers.
+
+1. [FastAPI Server](fastapi-webhook-server/README.md) -
+   A FastAPI implementation that handles PSTN (Public Switched Telephone
+   Network) and SIP (Session Initiation Protocol) calls using the Daily API.
+
+2. [Next.js Serverless](nextjs-webhook-server/README.md) -
+   A Next.js API implementation designed for deployment on Vercel's
+   serverless platform.
+
+Both implementations provide:
+
+- HMAC signature validation for pinless webhook
+- Structured logging
+- Support for dial-in and dial-out settings
+- Voicemail detection and call transfer functionality (coming soon)
+- Test request handling
+
+## Choosing an Implementation
+
+- Use the **FastAPI Server** if you:
+
+  - Need a standalone server
+  - Prefer Python and FastAPI
+  - Want to deploy to traditional hosting platforms
+
+- Use the **Next.js Serverless** implementation if you:
+  - Want serverless deployment
+  - Prefer JavaScript/TypeScript
+  - Already use Next.js and Vercel for other projects
+  - Need quick scaling and zero maintenance
+
+## Prerequisites
+
+### Environment Variables
+
+Both implementations require similar environment variables:
+
+- `PIPECAT_CLOUD_API_KEY`: Pipecat Cloud API Key, begins with pk\_\*
+- `AGENT_NAME`: Your Daily agent name
+- `PINLESS_HMAC_SECRET`: Your HMAC secret for request verification
+- `LOG_LEVEL`: (Optional) Logging level (defaults to 'info')
+
+See the individual README files in each implementation directory for
+specific setup instructions.
+
+### Phone number setup
+
+You can buy a phone number through the Pipecat Cloud Dashboard:
+
+1. Go to `Settings` > `Telephony`
+2. Follow the UI to purchase a phone number
+3. Configure the webhook URL to receive incoming calls (e.g. `https://my-webhook-url.com/api/dial`)
+
+Or purchase the number using Daily's
+[PhoneNumbers API](https://docs.daily.co/reference/rest-api/phone-numbers).
+
+```bash
+curl --request POST \
+--url https://api.daily.co/v1/domain-dialin-config \
+--header 'Authorization: Bearer $TOKEN' \
+--header 'Content-Type: application/json' \
+--data-raw '{
+	"type": "pinless_dialin",
+	"name_prefix": "Customer1",
+    "phone_number": "+1PURCHASED_NUM",
+	"room_creation_api": "https://example.com/api/dial",
+    "hold_music_url": "https://example.com/static/ringtone.mp3",
+	"timeout_config": {
+		"message": "No agent is available right now"
+	}
+}'
+```
+
+The API will return a static SIP URI (`sip_uri`) that can be called
+from other SIP services.
+
+### `room_creation_api`
+
+To make and receive calls currently you have to host a server that
+handles incoming calls. In the coming weeks, incoming calls will be
+directly handled within Daily and we will expose an endpoint similar
+to `{service}/start` that will manage this for you.
+
+In the meantime, the server described below serves as the webhook
+handler for the `room_creation_api`. Configure your pinless phone
+number or SIP interconnect to the `ngrok` tunnel or
+the actual server URL, append `/api/dial` to the webhook URL.
+
+## Example curl commands
+
+Note: Replace `http://localhost:3000` with your actual server URL and
+phone numbers with valid values for your use case.
+
+### Dialin Request
+
+The server will receive a request when a call is received from Daily.
+
+### Dialout Request
+
+Dial a number, will use any purchased number
+
+```bash
+curl -X POST http://localhost:3000/api/dial \
+  -H "Content-Type: application/json" \
+  -d '{
+    "dialout_settings": [
+      {
+        "phoneNumber": "+1234567890",
+      }
+    ]
+  }'
+```
+
+Dial a number with callerId, which is the UUID of a purchased number.
+
+```bash
+curl -X POST http://localhost:3000/api/dial \
+  -H "Content-Type: application/json" \
+  -d '{
+    "dialout_settings": [
+      {
+        "phoneNumber": "+1234567890",
+        "callerId": "purchased_phone_uuid"
+      }
+    ]
+  }'
+```
+
+Dial a number
+
+```bash
+curl -X POST http://localhost:3000/api/dial \
+  -H "Content-Type: application/json" \
+  -d '{
+    "dialout_settings": [
+      {
+        "phoneNumber": "+1234567890",
+        "callerId": "purchased_phone_uuid"
+      }
+    ]
+  }'
+```
+
+### Advanced Request with Voicemail Detection
+
+```bash
+curl -X POST http://localhost:3000/api/dial \
+  -H "Content-Type: application/json" \
+  -d '{
+    "To": "+1234567890",

+      {
+        "phoneNumber": "+1234567890",
+        "callerId": "purchased_phone_uuid"
+      }

+# FastAPI server for handling Daily PSTN/SIP Webhook
+
+A FastAPI server that handles PSTN (Public Switched Telephone Network) and SIP (Session Initiation Protocol) calls using the Daily API.
+
+## Setup
+
+1. Clone the repository
+
+2. Navigate to the `fastapi-webhook-server` directory:
+
+   ```bash
+   cd fastapi-webhook-server
+   ```
+
+3. Install dependencies:
+
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+4. Copy `env.example` to `.env`:
+
+   ```bash
+   cp env.example .env
+   ```
+
+5. Update `.env` with your credentials:
+
+   - `AGENT_NAME`: Your Daily agent name
+   - `PIPECAT_CLOUD_API_KEY`: Your Daily API key
+   - `PINLESS_HMAC_SECRET`: Your HMAC secret for request verification
+
+## Running the Server
+
+Start the server:
+
+```bash
+python server.py
+```
+
+The server will run on `http://localhost:7860` and you can expose it via ngrok for testing:
+
+```bash
+`ngrok http 7860`
+```
+
+> Tip: Use a subdomain for a consistent URL (e.g. `ngrok http -subdomain=mydomain http://localhost:7860`)
+
+## API Endpoints
+
+### GET /
+
+Health check endpoint that returns a "Hello, World!" message.
+
+### POST /api/dial
+
+Initiates a PSTN/SIP call with the following request body format:
+
+```json
+{
+  "To": "+14152251493",
+  "From": "+14158483432",
+  "callId": "string-contains-uuid",
+  "callDomain": "string-contains-uuid",
+  "dialout_settings": [
+    {
+      "phoneNumber": "+14158483432",
+      "callerId": "+14152251493"
+    }
+  ],
+  "voicemail_detection": {
+    "testInPrebuilt": true
+  },
+  "call_transfer": {
+    "mode": "dialout",
+    "speakSummary": true,
+    "storeSummary": true,
+    "operatorNumber": "+14152250006",
+    "testInPrebuilt": true
+  }
+}
+```
+
+#### Response
+
+Returns a JSON object containing:
+
+- `status`: Success/failure status
+- `data`: Response from Daily API
+- `room_properties`: Properties of the created Daily room
+
+## Error Handling
+
+- 401: Invalid signature
+- 400: Invalid authorization header (e.g. missing Daily API key in bot.py)
+- 405: Method not allowed (e.g. incorrect route on the webhook URL)
+- 500: Server errors (missing API key, network issues)
+- Other status codes are passed through from the Daily API

+# Next.js server for handling Daily PSTN/SIP Webhook
+
+Next.js API routes for handling Daily PSTN/SIP Pipecat requests.
+
+## Features
+
+- API endpoint for handling Daily PSTN/SIP Pipecat requests
+- HMAC signature validation
+- Structured logging with Pino
+- Support for dial-in and dial-out settings
+- Voicemail detection and call transfer functionality
+- Test request handling
+
+## Setup
+
+1. Clone the repository
+
+2. Navigate to the `nextjs-webhook-server` directory:
+
+   ```bash
+   cd nextjs-webhook-server
+   ```
+
+3. Install dependencies:
+
+   ```bash
+   npm install
+   ```
+
+4. Create `.env.local` file with your credentials:
+
+   ```bash
+   cp env.local.example .env.local
+   ```
+
+5. Update your `.env` with your secrets:
+
+   ```bash
+   PIPECAT_CLOUD_API_KEY=pk_*
+   AGENT_NAME=my-first-agent
+   PINLESS_HMAC_SECRET=your_hmac_secret
+   LOG_LEVEL=info
+   ```
+
+### Running the server
+
+Run the development server:
+
+```bash
+npm run dev
+```
+
+The server will run on `http://localhost:7860` and you can expose it via ngrok for testing:
+
+```bash
+`ngrok http 7860`
+```
+
+> Tip: Use a subdomain for a consistent URL (e.g. `ngrok http -subdomain=mydomain http://localhost:7860`)
+
+## API Endpoints
+
+### GET /api
+
+Returns a simple "Hello, World!" message with a cute cat emoji to verify the server is running.
+
+### POST /api/dial
+
+Handles dial-in and dial-out requests for Pipecat Cloud.
+
+#### Test Requests
+
+The endpoint handles test requests when a webhook is configured. Send a request with `"Test": "test"` to verify your setup:
+
+```json
+{
+  "Test": "test"
+}
+```
+
+#### Production Request Format
+
+```json
+{
+  // for dial-in from webhook
+  "To": "+14152251493",
+  "From": "+14158483432",
+  "callId": "string-contains-uuid",
+  "callDomain": "string-contains-uuid",
+  // for making a dial out to a phone or SIP
+  "dialout_settings": [
+    { "phoneNumber": "+14158483432", "callerId": "purchased_phone_uuid" },
+    { "sipUri": "sip:username@sip.hostname.com" }
+  ]
+}
+```
+
+## Deployment
+
+The application is configured for Vercel deployment:
+
+1. Push your code to a Git repository
+2. Import your project in Vercel dashboard
+3. Configure environment variables:
+   - `PIPECAT_CLOUD_API_KEY`
+   - `AGENT_NAME`
+   - `PINLESS_HMAC_SECRET`
+   - `LOG_LEVEL` (optional, defaults to 'info')
+4. Deploy!
+
+## Security
+
+- HMAC signature validation for request authentication
+- Environment variables for sensitive credentials
+- Method validation (POST only for /dial)

+# Smart Turn Detection Demo
+
+This demo showcases Pipecat's Smart Turn Detection feature - an advanced conversational turn detection system that uses machine learning to identify when a speaker has finished their turn in a conversation. Unlike basic Voice Activity Detection (VAD) which only detects speech vs. silence, Smart Turn detects natural conversational cues like intonation patterns, pacing, and linguistic signals.
+
+This demo uses the [pipecat-ai/smart-turn](https://huggingface.co/pipecat-ai/smart-turn) model - an open-source, community-driven conversational turn detection model designed to provide more natural turn-taking in voice interactions. The model is being hosted on Fal's infrastructure for GPU acceleration, offering inference times between 50-60ms.
+
+In the client UI, you can see the transcription messages along with the smart-turn model's prediction results in real-time.
+
+## Try the demo
+
+Try the hosted version of the demo here: https://pcc-smart-turn.vercel.app/.
+
+## Run the demo locally
+
+### Run the Server
+
+1. Set up and activate your virtual environment:
+
+   ```bash
+   python3 -m venv venv
+   source venv/bin/activate  # On Windows: venv\Scripts\activate
+   ```
+
+2. Install dependencies:
+
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+3. Create your .env file and set your env vars:
+
+   ```bash
+   cp env.example .env
+   ```
+
+   Keys to provide:
+
+   - GOOGLE_API_KEY
+   - CARTESIA_API_KEY
+   - DEEPGRAM_API_KEY
+   - DAILY_API_KEY
+   - FAL_SMART_TURN_API_KEY
+
+4. Run the server:
+
+   ```bash
+   LOCAL=1 python server.py
+   ```
+
+### Run the client
+
+1. Open a new terminal and navigate to the client directory:
+
+   ```bash
+   cd client
+   ```
+
+2. Install dependencies:
+
+   ```bash
+   npm install
+   ```
+
+3. Create your .env.local file:
+
+   ```bash
+   cp env.local.example .env.local
+   ```
+
+   > Note: No keys need to be modified. `NEXT_PUBLIC_API_BASE_URL` is already configured for local use.
+
+4. Start the development server:
+
+   ```bash
+   npm run dev
+   ```
+
+5. Open [http://localhost:3000](http://localhost:3000) in your browser.
+
+## Deploy the app
+
+### Deploy the server to Pipecat Cloud
+
+1. Navigate to server
+
+   ```bash
+   cd server
+   ```
+
+2. You should already have a .env set up from running locally. If not, do that now.
+
+3. Update your build and deploy scripts.
+
+   - In build.sh, set `DOCKER_USERNAME` and `AGENT_NAME`.
+   - In pcc-deploy.toml, set `image`, which specifies where your Docker image is stored.
+
+4. Build your Docker image by running the build script:
+
+   ```bash
+   ./build.sh
+   ```
+
+   > Note: This builds, tags and pushes your docker image and assumes Docker Hub is the container registry.
+
+5. Make sure you have the Pipecat Cloud CLI installed:
+
+   ```bash
+   pip install pipecatcloud
+   ```
+
+6. Login via the Pipecat Cloud CLI:
+
+   ```bash
+   pcc auth login
+   ```
+
+   > Note: If you don't have an account, sign up at https://pipecat.daily.co.
+
+7. Add a secrets set:
+
+   ```bash
+   pcc secrets set pcc-smart-turn-secrets --file .env
+   ```
+
+8. Deploy your agent:
+
+   ```bash
+   pcc deploy
+   ```
+
+   > Note: This uses your pcc-deploy.toml settings. Modify as needed.
+
+### Deploy the client to Vercel
+
+This project uses TypeScript, React, and Next.js, making it a perfect fit for [Vercel](https://vercel.com/).
+
+- In your client directory, install Vercel's CLI tool: `npm install -g vercel`
+- Verify it's installed using `vercel --version`
+- Log in your Vercel account using `vercel login`
+- Deploy your client to Vercel using `vercel`
+
+Follow the vercel prompts to deploy your project.
+
+### Test your deployed app
+
+Now with the client and server deployed, you can join the call using your Vercel URL.
+
+See the debug information for the Smart Turn data. It prints a log line for each smart-turn inference:
+
+```
+Smart Turn: COMPLETE, Probability: 95.3%, Model inference: 65.23ms, Server processing: 82.09ms, End-to-end: 245.43ms
+```
