update README with KoalaFilter

This seems necessary because of how pytest works. If a task is cancelled, pytest
will know the task has been cancelled even if # `asyncio.CancelledError` is
handled internally in the task.

 ### Added
 
-- It is now possible to specify the asyncio event loop that a `PipelineTask` and
-  all the processors should run on by passing it as a new argument to the
-  `PipelineRunner`. This could allow running pipelines in multiple threads each
-  one with its own event loop.
-
-- Added a new `utils.TaskManager`. Instead of a global task manager we now have
-  a task manager per `PipelineTask`. In the previous version the task manager
-  was global, so running multiple simultaneous `PipelineTask`s could result in
-  dangling task warnings which were not actually true. In order, for all the
-  processors to know about the task manager, we pass it through the
-  `StartFrame`. This means that processors should create tasks when they receive
-  a `StartFrame` but not before (because they don't have a task manager yet).
-
-- Added `TelnyxFrameSerializer` to support Telnyx calls. A full running example
-  has also been added to `examples/telnyx-chatbot`.
-
-- Allow pushing silence audio frames before `TTSStoppedFrame`. This might be
-  useful for testing purposes, for example, passing bot audio to an STT service
-  which usually needs additional audio data to detect the utterance stopped.
-
-- `TwilioSerializer` now supports transport message frames. With this we can
-  create Twilio emulators.
-
-- Added a new transport: `WebsocketClientTransport`.
-
-- Added a `metadata` field to `Frame` which makes it possible to pass custom
-  data to all frames.
-
-- Added `test/utils.py` inside of pipecat package.
-
-### Changed
-
-- Improved the language checking logic in `ElevenLabsTTSService` and
-  `ElevenLabsHttpTTSService` to properly handle language codes based on model
-  compatibility, with appropriate warnings when language codes cannot be
-  applied.
-
-- Updated `GoogleLLMContext` to support pushing `LLMMessagesUpdateFrame`s that
-  contain a combination of function calls, function call responses, system
-  messages, or just messages.
-
-### Fixed
-
-- Fixed an issue where `ElevenLabsTTSService` messages would return a 1009
-  websocket error by increasing the max message size limit to 16MB.
-
-- Fixed a `DailyTransport` issue that would cause events to be triggered before
-  join finished.
-
-- Fixed a `PipelineTask` issue that was preventing processors to be cleaned up
-  after cancelling the task.
-
-- Fixed an issue where queuing a `CancelFrame` to a pipeline task would not
-  cause the task to finish. However, using `PipelineTask.cancel()` is still the
-  recommended way to cancel a task.
-
-### Other
-
-- Updated all examples to use `task.cancel()` instead of pushing an `EndFrame`
-  when a participant leaves/disconnects. If you push an `EndFrame` this will
-  cause the bot to run through everything that is internally queued (which could
-  take seconds). Instead, if a participant disconnects there is nothing else to
-  be sent and therefore we should stop immediately.
-
-## [0.0.54] - 2025-01-27
-
-### Added
-
-- In order to create tasks in Pipecat frame processors it is now recommended to
-  use `FrameProcessor.create_task()` (which uses the new
-  `utils.asyncio.create_task()`). It takes care of uncaught exceptions, task
-  cancellation handling and task management. To cancel or wait for a task there
-  is `FrameProcessor.cancel_task()` and `FrameProcessor.wait_for_task()`. All of
-  Pipecat processors have been updated accordingly. Also, when a pipeline runner
-  finishes, a warning about dangling tasks might appear, which indicates if any
-  of the created tasks was never cancelled or awaited for (using these new
-  functions).
-
-- It is now possible to specify the period of the `PipelineTask` heartbeat
-  frames with `heartbeats_period_secs`.
-
-- Added `DailyMeetingTokenProperties` and `DailyMeetingTokenParams` Pydantic models
-  for meeting token creation in `get_token` method of `DailyRESTHelper`.
-
-- Added `enable_recording` and `geo` parameters to `DailyRoomProperties`.
-
-- Added `RecordingsBucketConfig` to `DailyRoomProperties` to upload recordings to a custom AWS bucket.
-
-### Changed
-
-- Enhanced `UserIdleProcessor` with retry functionality and control over idle
-  monitoring via new callback signature `(processor, retry_count) -> bool`.
-  Updated the `17-detect-user-idle.py` to show how to use the `retry_count`.
-
-- Add defensive error handling for `OpenAIRealtimeBetaLLMService`'s audio
-  truncation. Audio truncation errors during interruptions now log a warning
-  and allow the session to continue instead of throwing an exception.
-
-- Modified `TranscriptProcessor` to use TTS text frames for more accurate assistant
-  transcripts. Assistant messages are now aggregated based on bot speaking boundaries
-  rather than LLM context, providing better handling of interruptions and partial
-  utterances.
-
-- Updated foundational examples `28a-transcription-processor-openai.py`,
-  `28b-transcript-processor-anthropic.py`, and
-  `28c-transcription-processor-gemini.py` to use the updated
-  `TranscriptProcessor`.
-
-### Fixed
-
-- Fixed an `GeminiMultimodalLiveLLMService` issue that was preventing the user
-  to push initial LLM assistant messages (using `LLMMessagesAppendFrame`).
-
-- Added missing `FrameProcessor.cleanup()` calls to `Pipeline`,
-  `ParallelPipeline` and `UserIdleProcessor`.
-
-- Fixed a type error when using `voice_settings` in `ElevenLabsHttpTTSService`.
-
-- Fixed an issue where `OpenAIRealtimeBetaLLMService` function calling resulted
-  in an error.
-
-- Fixed an issue in `AudioBufferProcessor` where the last audio buffer was not
-  being processed, in cases where the `_user_audio_buffer` was smaller than the
-  buffer size.
-
-### Performance
-
-- Replaced audio resampling library `resampy` with `soxr`. Resampling a 2:21s
-  audio file from 24KHz to 16KHz took 1.41s with `resampy` and 0.031s with
-  `soxr` with similar audio quality.
-
-### Other
-
-- Added initial unit test infrastructure.
-
-## [0.0.53] - 2025-01-18
-
-### Added
-
-- Added `ElevenLabsHttpTTSService` which uses EleveLabs' HTTP API instead of the
-  websocket one.
-
-- Introduced pipeline frame observers. Observers can view all the frames that go
-  through the pipeline without the need to inject processors in the
-  pipeline. This can be useful, for example, to implement frame loggers or
-  debuggers among other things. The example
-  `examples/foundational/30-observer.py` shows how to add an observer to a
-  pipeline for debugging.
-
-- Introduced heartbeat frames. The pipeline task can now push periodic
-  heartbeats down the pipeline when `enable_heartbeats=True`. Heartbeats are
-  system frames that are supposed to make it all the way to the end of the
-  pipeline. When a heartbeat frame is received the traversing time (i.e. the
-  time it took to go through the whole pipeline) will be displayed (with TRACE
-  logging) otherwise a warning will be shown. The example
-  `examples/foundational/31-heartbeats.py` shows how to enable heartbeats and
-  forces warnings to be displayed.
-
-- Added `LLMTextFrame` and `TTSTextFrame` which should be pushed by LLM and TTS
-  services respectively instead of `TextFrame`s.
-
-- Added `OpenRouter` for OpenRouter integration with an OpenAI-compatible
-  interface. Added foundational example `14m-function-calling-openrouter.py`.
-
-- Added a new `WebsocketService` based class for TTS services, containing
-  base functions and retry logic.
-
-- Added `DeepSeekLLMService` for DeepSeek integration with an OpenAI-compatible
-  interface. Added foundational example `14l-function-calling-deepseek.py`.
-
-- Added `FunctionCallResultProperties` dataclass to provide a structured way to
-  control function call behavior, including:
-
-  - `run_llm`: Controls whether to trigger LLM completion
-  - `on_context_updated`: Optional callback triggered after context update
-
-- Added a new foundational example `07e-interruptible-playht-http.py` for easy
-  testing of `PlayHTHttpTTSService`.
-
-- Added support for Google TTS Journey voices in `GoogleTTSService`.
-
-- Added `29-livekit-audio-chat.py`, as a new foundational examples for
-  `LiveKitTransportLayer`.
-
-- Added `enable_prejoin_ui`, `max_participants` and `start_video_off` params
-  to `DailyRoomProperties`.
-
-- Added `session_timeout` to `FastAPIWebsocketTransport` and
-  `WebsocketServerTransport` for configuring session timeouts (in
-  seconds). Triggers `on_session_timeout` for custom timeout handling.
-  See [examples/websocket-server/bot.py](https://github.com/pipecat-ai/pipecat/blob/main/examples/websocket-server/bot.py).
-
-- Added the new modalities option and helper function to set Gemini output
-  modalities.
-
-- Added `examples/foundational/26d-gemini-multimodal-live-text.py` which is
-  using Gemini as TEXT modality and using another TTS provider for TTS process.
-
-### Changed
-
-- Modified `UserIdleProcessor` to start monitoring only after first
-  conversation activity (`UserStartedSpeakingFrame` or
-  `BotStartedSpeakingFrame`) instead of immediately.
-
-- Modified `OpenAIAssistantContextAggregator` to support controlled completions
-  and to emit context update callbacks via `FunctionCallResultProperties`.
-
-- Added `aws_session_token` to the `PollyTTSService`.
-
-- Changed the default model for `PlayHTHttpTTSService` to `Play3.0-mini-http`.
-
-- `api_key`, `aws_access_key_id` and `region` are no longer required parameters
-  for the PollyTTSService (AWSTTSService)
-
-- Added `session_timeout` example in `examples/websocket-server/bot.py` to
-  handle session timeout event.
-
-- Changed `InputParams` in
-  `src/pipecat/services/gemini_multimodal_live/gemini.py` to support different
-  modalities.
-
-- Changed `DeepgramSTTService` to send `finalize` event whenever VAD detects
-  `UserStoppedSpeakingFrame`. This helps in faster transcriptions and clearing
-  the `Deepgram` audio buffer.
-
-### Fixed
-
-- Fixed an issue where `DeepgramSTTService` was not generating metrics using
-  pipeline's VAD.
-
-- Fixed `UserIdleProcessor` not properly propagating `EndFrame`s through the
-  pipeline.
-
-- Fixed an issue where websocket based TTS services could incorrectly terminate
-  their connection due to a retry counter not resetting.
-
-- Fixed a `PipelineTask` issue that would cause a dangling task after stopping
-  the pipeline with an `EndFrame`.
-
-- Fixed an import issue for `PlayHTHttpTTSService`.
-
-- Fixed an issue where languages couldn't be used with the `PlayHTHttpTTSService`.
-
-- Fixed an issue where `OpenAIRealtimeBetaLLMService` audio chunks were hitting
-  an error when truncating audio content.
-
-- Fixed an issue where setting the voice and model for `RimeHttpTTSService`
-  wasn't working.
-
-- Fixed an issue where `IdleFrameProcessor` and `UserIdleProcessor` were getting
-  initialized before the start of the pipeline.
-
-## [0.0.52] - 2024-12-24
-
-### Added
-
-- Constructor arguments for GoogleLLMService to directly set tools and tool_config.
-
-- Smart turn detection example (`22d-natural-conversation-gemini-audio.py`) that
-  leverages Gemini 2.0 capabilities ().
-  (see https://x.com/kwindla/status/1870974144831275410)
-
 - Added `DailyTransport.send_dtmf()` to send dial-out DTMF tones.
 
 - Added `DailyTransport.sip_call_transfer()` to forward SIP and PSTN calls to

-# Bot ready signaling
-
-A simple Pipecat example demonstrating how to handle signaling between the client and the bot, 
-ensuring that the bot starts sending audio only when the client is available, 
-thereby avoiding the risk of cutting off the beginning of the audio.
-
-## Quick Start
-
-### First, start the bot server:
-
-1. Navigate to the server directory:
-   ```bash
-   cd server
-   ```
-2. Create and activate a virtual environment:
-   ```bash
-   python3 -m venv venv
-   source venv/bin/activate  # On Windows: venv\Scripts\activate
-   ```
-3. Install requirements:
-   ```bash
-   pip install -r requirements.txt
-   ```
-4. Copy env.example to .env and configure:
-   - Add your API keys
-5. Start the server:
-   ```bash
-   python server.py
-   ```
-
-### Next, connect using the client app:
-
-For client-side setup, refer to the [JavaScript Guide](client/javascript/README.md).
-
-## Important Note
-
-Ensure the bot server is running before using any client implementations.
-
-## Requirements
-
-- Python 3.10+
-- Node.js 16+ (for JavaScript)
-- Daily API key
-- Cartesia API key
-- Modern web browser with WebRTC support

-
-## Setup
-
-1. Run the bot server. See the [server README](../../README).
-
-2. Navigate to the `client/javascript` directory:
-
-```bash
-cd client/javascript
-```
-
-3. Install dependencies:
-
-```bash

-# Bot ready signaling Server
-
-A FastAPI server that manages bot instances and provide endpoint for Pipecat client connections.
-
-## Endpoints
-
-- `POST /connect` - Pipecat client connection endpoint
-
-## Environment Variables
-
-Copy `env.example` to `.env` and configure:
-
-```ini
-# Required API Keys
-DAILY_API_KEY=           # Your Daily API key
-CARTESIA_API_KEY=        # Your Cartesia API key
-
-# Optional Configuration
-DAILY_API_URL=           # Optional: Daily API URL (defaults to https://api.daily.co/v1)
-DAILY_SAMPLE_ROOM_URL=   # Optional: Fixed room URL for development
-HOST=                    # Optional: Host address (defaults to 0.0.0.0)
-FAST_API_PORT=           # Optional: Port number (defaults to 7860)
-```
-
-## Running the Server
-
-Set up and activate your virtual environment:
-
-```bash
-python3 -m venv venv
-source venv/bin/activate  # On Windows: venv\Scripts\activate
-```
-
-Install dependencies:
-
-```bash
-pip install -r requirements.txt
-```
-
-If you want to use the local version of `pipecat` in this repo rather than the last published version, also run:
-
-```bash
-pip install --editable "../../../[daily,cartesia,openai]"
-```
-
-Run the server:
-
-```bash
-python server.py
-```

+# Dialin example
+
+Example project that demonstrates how to add phone number dialin to your Pipecat bots. We include examples for both Daily (`bot_daily.py`) and Twilio (`bot_twilio.py`), depending on who you want to use as a phone vendor.
+
+- 🔁 Transport: Daily WebRTC
+- 💬 Speech-to-Text: Deepgram via Daily transport
+- 🤖 LLM: GPT4-o / OpenAI
+- 🔉 Text-to-Speech: ElevenLabs
+
+#### Should I use Daily or Twilio as a vendor?
+
+If you're starting from scratch, using Daily to provision phone numbers alongside Daily as a transport offers some convenience (such as automatic call forwarding.)
+
+If you already have Twilio numbers and workflows that you want to connect to your Pipecat bots, there is some additional configuration required (you'll need to create a `on_dialin_ready` and use the Twilio client to trigger the forward.)
+
+You can read more about this, as well as see respective walkthroughs in our docs.
+
+## Setup
+
+```shell
+# Install the requirements
+pip install -r requirements.txt
+
+# Setup your env
+mv env.example .env
+```
+
+## Using Daily numbers
+
+Run `bot_runner.py` to handle incoming HTTP requests:
+
+`python bot_runner.py --host localhost`
+
+Then target the following URL:
+
+`POST /daily_start_bot`
+
+For more configuration options, please consult Daily's API documentation.
+
+
+## Using Twilio numbers
+
+As above, but target the following URL:
+
+`POST /twilio_start_bot`
+
+For more configuration options, please consult Twilio's API documentation.
+
+## Deployment example
+
+A Dockerfile is included in this demo for convenience. Here is an example of how to build and deploy your bot to [fly.io](https://fly.io).
+
+*Please note: This demo spawns agents as subprocesses for convenience / demonstration purposes. You would likely not want to do this in production as it would limit concurrency to available system resources. For more information on how to deploy your bots using VMs, refer to the Pipecat documentation.*
+
+### Build the docker image
+
+`docker build -t tag:project .`
+
+### Launch the fly project
+
+`mv fly.example.toml fly.toml`
+
+`fly launch` (using the included fly.toml)
+
+### Setup your secrets on Fly
+
+Set the necessary secrets (found in `env.example`)
+
+`fly secrets set DAILY_API_KEY=... OPENAI_API_KEY=... ELEVENLABS_API_KEY=... ELEVENLABS_VOICE_ID=...`
+
+If you're using Twilio as a number vendor:
+
+`fly secrets set TWILIO_ACCOUNT_SID=... TWILIO_AUTH_TOKEN=...`
+
+### Deploy!
+
+`fly deploy`
+
+## Need to do something more advanced?
+
+This demo covers the basics of bot telephony. If you want to know more about working with PSTN / SIP, please ping us on [Discord](https://discord.gg/pipecat).
