Azure Communication Services - Python SDK Call Media not working with CallConnectionClient
Hi team, I’m working on a FastAPI service that uses Azure Communication Services Call Automation (Python SDK) to handle outbound PSTN calls and real-time speech interaction. So far it is able to make phone calls but not able to do media handling part during conversation. Environment: Python version: 3.12-slim Package: azure-communication-callautomation (version: 1.4.0) Hosting: Azure Container Apps speech cognitive resource is connected to azure communication services https://drive.google.com/file/d/1uC2S-LNx_Ybpp1QwOCtqFS9pwA84mK7h/view?usp=drive_link What I’m trying to do: Place an outbound call to a PSTN number Play a greeting (TextSource) when the call is connected Start continuous speech recognition, forward transcript to an AI endpoint, then play the response back Code snippet: # Play greeting try: call_connection = client.get_call_connection(call_id) call_media = call_connection.call_media() call_media.play_to_all( play_source, operation_context="welcome-play" ) print("Played welcome greeting.") except Exception as e: print("Play Greeting Failed: ", str(e)) # start Recognition participants = list(call_connection.list_participants()) for p in participants: if isinstance(p.identifier, PhoneNumberIdentifier): active_participants[call_id] = p.identifier try: call_connection = client.get_call_connection(call_id) call_media = call_connection.call_media() call_media.start_recognizing_media( target_participant=p.identifier, input_type="speech", interrupt_call_media_operation=True, operation_context="speech-recognition" ) print("Started recognition immediately after call connected.") except Exception as e: print("Recognition start failed:", str(e)) break target_participant = active_participants.get(call_id) if not target_participant: print(f"No PSTN participant found for call {call_id}, skipping recognition.") Issue: When the CallConnected event fires,, I get different errors depending on which method I try: 'CallConnectionClient' object has no attribute 'call_media' 'CallConnectionClient' object has no attribute 'get_call_media_operations' 'CallConnectionClient' object has no attribute 'play_to_all' 'CallConnectionClient' object has no attribute 'get_call_media_client' 'CallConnectionClient' object has no attribute 'get_call_media' Also some import errors: ImportError: cannot import name 'PlayOptions' from 'azure.communication.callautomation' ImportError: cannot import name 'RecognizeOptions' from 'azure.communication.callautomation' ImportError: cannot import name 'CallMediaRecognizeOptions' from 'azure.communication.callautomation' ImportError: cannot import name 'CallConnection' ... Did you mean: 'CallConnectionState'? This makes me unsure which API is the correct/updated way to access play_to_all and start_recognizing_media. https://drive.google.com/file/d/1xI-sWil0OKfAfGwjIgG25eD7CEK95rKc/view?usp=drive_link Questions: What is the current supported way to access call media operations (play / speech recognition) in the Python SDK? Are there breaking changes between SDK versions that I should be aware of? Should I upgrade to a specific minimum version to ensure .call_media works? Thanks in advance!
