@millions-hair-24956 hey my egress start recordıng via phone ringing , i fuser dont pick up phone ıt contıunes rıngıng , how to prevent thıs ? there ıs no tracj subrıce on outbound calls so my code force start . await asyncio.sleep(2) if not agent_started[0]: logger.info("Track subscription not triggered, forcing voice pipeline agent start") run_voice_pipeline_agent(ctx, participant, _instructions) agent_started[0] = True if not egress_id: logger.debug("Track subscription not triggered, forcing recording start") egress_id = await record_call(ctx, phone_number) so my record ıs begınııng from ringing. how can ı start egress healty ? i want to start record when phone participant joın (i mean when agent start speak ) def on_track_subscribed(track, publication, participant): nonlocal agent_started, egress_id logger.debug(f"track_subscribed triggered for participant: {participant.identity}, track kind: {track> if participant.identity == user_identity and track.kind == rtc.TrackKind.KIND_AUDIO: logger.info("SIP audio track subscribed") if not agent_started[0]: logger.info("Starting voice pipeline agent from track subscription") run_voice_pipeline_agent(ctx, participant, _instructions) agent_started[0] = True if not egress_id: logger.debug("Starting recording task from track subscription") task = asyncio.create_task(record_call(ctx, phone_number)) task.add_done_callback(lambda fut: globals().update(egress_id=fut.result()))

It seems likely that you want to start recording only when the phone participant has joined and the agent begins speaking. Based on the information from the LiveKit documentation, you can use the
track_subscribed
event to trigger the start of your recording. This event is fired when a track is successfully subscribed to, indicating that the participant is ready to communicate. To ensure that the recording starts only when the participant joins, you should wait for the
track_subscribed
event for the audio track of the SIP participant. This will ensure that the recording does not start during the ringing phase. You can modify your code to check for the
track_subscribed
event and start the recording only when this event is triggered for the audio track of the SIP participant. Would you like more detailed guidance on implementing this approach? Sources: - LiveKit documentation 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

but if this is outbound call , there ıs no event lıke track-subsribed. so i force statrt egress. @millions-hair-24956

It seems likely that for outbound calls, the
track_subscribed
event might not be triggered as expected. In such cases, you can use the
sip.callStatus
attribute to determine when the call is active. According to the LiveKit SIP documentation, the
sip.callStatus
changes to
active
when the SIP participant subscribes to any remote audio tracks, indicating that the call is connected. You can listen for changes in the
sip.callStatus
attribute to start the recording. This approach ensures that the recording begins only when the call is active, avoiding the ringing phase. Here's a conceptual approach: 1. Monitor
sip.callStatus
: Use the
participant_attributes_changed
event to monitor changes in the
sip.callStatus
attribute. 2. Start Recording: When
sip.callStatus
changes to
active
, initiate the recording process. Would you like more detailed guidance on implementing this approach? Sources: - LiveKit SIP documentation 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

give me a code snippet @millions-hair-24956
g
Certainly! Here's a code snippet that demonstrates how to start recording when the
sip.callStatus
changes to `active`:
Copy code
async def entrypoint(ctx: JobContext):
    call_active_event = asyncio.Event()

    @ctx.room.on("participant_attributes_changed")
    def on_attributes_changed(changed_attributes: dict[str, str], participant):
        if changed_attributes.get("sip.callStatus") == "active":
            call_active_event.set()

    await ctx.connect(auto_subscribe=AutoSubscribe.AUDIO_ONLY)
    participant = await ctx.wait_for_participant()

    # Wait for the call to become active
    await call_active_event.wait()

    # Start recording once the call is active
    egress_id = await record_call(ctx, participant.identity)
    logger.info(f"Recording started with egress ID: {egress_id}")

async def record_call(ctx, participant_identity):
    # Implement your recording logic here
    pass
This snippet sets up a listener for the
participant_attributes_changed
event to detect when the
sip.callStatus
becomes
active
, indicating that the call is connected. Once the status is active, it starts the recording. Would you like more details on any part of this code?
