 ## Known limitations
 - In-band DTMF isn't supported. Use RFC 2833 DTMF instead.
 - Text-to-Speech text prompts support a maximum of 4000 characters, if your prompt is longer than this we suggest using SSML for Text-to-Speech based play actions.
+- When recording is enabled speech input is recorded for 1:1 calls, but is not recorded in group calls.
 - For scenarios where you exceed your Speech service quota limit, you can request to increase this limit by following the steps outlined in [Speech services quotas and limits](/azure/ai-services/speech-service/speech-services-quotas-and-limits).
