 ### Added
 
+- Add the ability to send DTMF to `LiveKitTransport`.
+
 - Expanded support for universal `LLMContext` to the Anthropic LLM service.
   Using the universal `LLMContext` and associated `LLMContextAggregatorPair` is
   a pre-requisite for using `LLMSwitcher` to switch between LLMs at runtime.
