@millions-hair-24956 i am tryıng to tyr egress servıce for outbound calls . how can i get sip participant status , and whehn sip participant active i start egress servıce start record ? give me code snippet

It seems likely that you can monitor the SIP participant's status using the

sip.callStatus

attribute. When the status is

active

, it indicates that the call is connected, and you can start the egress service to record the call. Here's a basic code snippet to help you get started:

import asyncio
from livekit import api

async def start_egress_when_active(participant):
    if participant.kind == api.ParticipantKind.SIP:
        while True:
            if participant.attributes.get('sip.callStatus') == 'active':
                await start_audio_egress(participant.room_name, participant.identity)
                break
            await asyncio.sleep(1)  # Check every second

async def start_audio_egress(room_name, participant_identity):
    req = api.ParticipantEgressRequest(
        room_name=room_name,
        identity=participant_identity,
        file_outputs=[
            api.EncodedFileOutput(
                filepath=f"{room_name}/{participant_identity}/audio_recording.mp3",
                s3=api.S3Upload(
                    bucket="my_bucket_name",
                    region="my_region_name",
                    access_key="my_access_key",
                    secret="my_secret",
                    force_path_style=True,
                ),
            )
        ]
    )

    try:
        egress_info = await lkapi.egress.start_participant_egress(req)
        print(f"Egress started: {egress_info.egress_id}")
        return egress_info
    except Exception as e:
        print(f"Failed to start egress: {e}")
        raise

This code snippet checks the

sip.callStatus

attribute of a SIP participant and starts the egress service when the status is

active

. Would you like more details on this process? Sources: - SIP participant attributes 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

is it prod -ready becasue chengin it every 1 seconds too obvious .

Polling every second might not be the most efficient approach for a production environment. Instead, you can listen for the

participant_attributes_changed

event to detect when the

sip.callStatus

changes to

active

. This event-driven approach is more efficient and reduces unnecessary polling. Here's an updated code snippet using event listeners:

import asyncio
from livekit import api

async def monitor_participant_status(ctx):
    call_response_event = asyncio.Event()

    @ctx.room.on("participant_attributes_changed")
    def on_attributes_changed(changed_attributes, participant):
        if changed_attributes.get("sip.callStatus") == "active":
            call_response_event.set()

    await ctx.connect(auto_subscribe=api.AutoSubscribe.AUDIO_ONLY)
    participant = await ctx.wait_for_participant()
    await asyncio.wait_for(call_response_event.wait(), timeout=60)  # Wait for up to 60 seconds

    await start_audio_egress(ctx.room.name, participant.identity)

async def start_audio_egress(room_name, participant_identity):
    req = api.ParticipantEgressRequest(
        room_name=room_name,
        identity=participant_identity,
        file_outputs=[
            api.EncodedFileOutput(
                filepath=f"{room_name}/{participant_identity}/audio_recording.mp3",
                s3=api.S3Upload(
                    bucket="my_bucket_name",
                    region="my_region_name",
                    access_key="my_access_key",
                    secret="my_secret",
                    force_path_style=True,
                ),
            )
        ]
    )

    try:
        egress_info = await lkapi.egress.start_participant_egress(req)
        print(f"Egress started: {egress_info.egress_id}")
        return egress_info
    except Exception as e:
        print(f"Failed to start egress: {e}")
        raise

This approach uses the

participant_attributes_changed

event to trigger the egress service when the call status becomes

active

, making it more suitable for production. Would you like more details on implementing this? Sources: - https://livekit-users.slack.com/archives/C07FRP66XGE/p1731592376.663589 - https://docs.livekit.io/home/client/data/ 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

lets do this way when sip call status actıve start record , when si,p call status hangup stop record . gıve me code snıppet @millions-hair-24956

To handle starting and stopping the recording based on the SIP call status, you can listen for the

participant_attributes_changed

event to detect changes in the

sip.callStatus

attribute. Here's a code snippet that demonstrates this approach:

import asyncio
from livekit import api

async def monitor_participant_status(ctx):
    egress_info = None

    @ctx.room.on("participant_attributes_changed")
    def on_attributes_changed(changed_attributes, participant):
        nonlocal egress_info
        call_status = changed_attributes.get("sip.callStatus")

        if call_status == "active" and egress_info is None:
            egress_info = asyncio.create_task(start_audio_egress(ctx.room.name, participant.identity))
        elif call_status == "hangup" and egress_info is not None:
            asyncio.create_task(stop_audio_egress(egress_info))

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

async def start_audio_egress(room_name, participant_identity):
    req = api.ParticipantEgressRequest(
        room_name=room_name,
        identity=participant_identity,
        file_outputs=[
            api.EncodedFileOutput(
                filepath=f"{room_name}/{participant_identity}/audio_recording.mp3",
                s3=api.S3Upload(
                    bucket="my_bucket_name",
                    region="my_region_name",
                    access_key="my_access_key",
                    secret="my_secret",
                    force_path_style=True,
                ),
            )
        ]
    )

    try:
        egress_info = await lkapi.egress.start_participant_egress(req)
        print(f"Egress started: {egress_info.egress_id}")
        return egress_info
    except Exception as e:
        print(f"Failed to start egress: {e}")
        raise

async def stop_audio_egress(egress_info):
    try:
        await lkapi.egress.stop_egress(egress_info.egress_id)
        print(f"Egress stopped: {egress_info.egress_id}")
    except Exception as e:
        print(f"Failed to stop egress: {e}")
        raise

This code listens for changes in the

sip.callStatus

attribute and starts recording when the status is

active

and stops when it is

hangup

It seems likely that the error you're encountering is due to attempting to register an asynchronous callback using the

.on()

method, which only supports synchronous callbacks. To resolve this, you should use

asyncio.create_task

within your synchronous callback to handle any asynchronous operations. Here's how you can modify your code:

import asyncio
from livekit import api

async def monitor_participant_status(ctx):
    egress_info = None

    def on_attributes_changed(changed_attributes, participant):
        nonlocal egress_info
        call_status = changed_attributes.get("sip.callStatus")

        if call_status == "active" and egress_info is None:
            egress_info = asyncio.create_task(start_audio_egress(ctx.room.name, participant.identity))
        elif call_status == "hangup" and egress_info is not None:
            asyncio.create_task(stop_audio_egress(egress_info))

    ctx.room.on("participant_attributes_changed", on_attributes_changed)

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

async def start_audio_egress(room_name, participant_identity):
    req = api.ParticipantEgressRequest(
        room_name=room_name,
        identity=participant_identity,
        file_outputs=[
            api.EncodedFileOutput(
                filepath=f"{room_name}/{participant_identity}/audio_recording.mp3",
                s3=api.S3Upload(
                    bucket="my_bucket_name",
                    region="my_region_name",
                    access_key="my_access_key",
                    secret="my_secret",
                    force_path_style=True,
                ),
            )
        ]
    )

    try:
        egress_info = await lkapi.egress.start_participant_egress(req)
        print(f"Egress started: {egress_info.egress_id}")
        return egress_info
    except Exception as e:
        print(f"Failed to start egress: {e}")
        raise

async def stop_audio_egress(egress_info):
    try:
        await lkapi.egress.stop_egress(egress_info.egress_id)
        print(f"Egress stopped: {egress_info.egress_id}")
    except Exception as e:
        print(f"Failed to stop egress: {e}")
        raise

This code uses a synchronous callback for the

participant_attributes_changed

event and creates tasks for asynchronous operations. Would you like more details on this implementation? Sources: - https://livekit-users.slack.com/archives/C07FRP66XGE/p1730288245.597009 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.
