during the initialization of the inference executor in LiveKit agents can be addressed with the following steps:
• Increase Initialization Timeout: Adjust the initialize_process_timeout
in WorkerOptions
to allow more time for initialization.
• Check Network Connectivity: Ensure there are no network issues, especially if the inference executor depends on external services or downloads.
• Optimize System Resources: Monitor CPU and memory usage. High system load can delay initialization. Adjust resource limits or redistribute tasks if necessary.
• Adjust Executor Configuration: Modify parameters like ping_interval
and high_ping_threshold
to allow more time for responses.
• Review Logs: Look for underlying exceptions or errors during initialization that might not be properly logged.
• Test with Different Methods: Some inference methods may require more resources. Testing with alternative methods can help identify if the issue is method-specific.

with the local_track_published
event. This usually happens when there’s a mismatch between the track info in the event and the local participant’s track publications. Don’t worry, here are some friendly steps to help you fix it:
1. Handle Race Conditions: Try adding some retry logic to cover cases where the event fires before the track is registered. A short delay and retry can do wonders here.
2. Register Event Handlers Early: Make sure your event handlers are set up before you connect to the room and publish tracks. This helps catch events right on time.
3. Defensive Programming: It’s a good idea to check if the track publication actually exists in track_publications
before you access it, just to be safe.
4. Validate Event Data: Double-check that the event includes valid data, like a proper publication.sid
and track object.
5. Monitor Connection State: Confirm that the room is fully connected before handling any events to avoid surprises.
Also, turning on debug logging and making sure you’re using the latest LiveKit SDK can really help spot and fix timing issues. If you want, I’m here to help you walk through any of these steps!

08/07/2025, 12:14 PMAttributeError: 'Room' object has no attribute 'wait_for_participant_join'
pops up because the LiveKit Python SDK’s Room
class doesn’t actually have a method called wait_for_participant_join
. No worries though—I’ve got some ways you can handle participant connections smoothly:
1. Use Event Listeners: You can listen for the "participant_connected"
event like this:
def on_participant_connected(participant):
print(f"Participant connected: {participant.identity}")
room.on("participant_connected", on_participant_connected)
2. Create Custom Waiting Logic: If you want to wait in a blocking way, here’s a neat asyncio approach:
async def wait_for_participant(room):
fut = asyncio.Future()
def _on_participant_connected(participant):
if not fut.done():
fut.set_result(participant)
room.on("participant_connected", _on_participant_connected)
try:
return await fut
finally:
room.off("participant_connected", _on_participant_connected)
3. Use Utility Functions: If you’re working with LiveKit Agents, there’s a handy wait_for_participant
utility function you can use:
from livekit.agents.utils import wait_for_participant
participant = await wait_for_participant(room)
4. JobContext Method: And if you’re inside an agent’s job context, you can simply call the built-in waitForParticipant
method:
participant = await job_context.wait_for_participant()

in the local_track_published
event and a participant disconnect that’s causing the agent session to close. No worries, here’s a friendly walkthrough to help you fix them:
1. *Fix the KeyError:*`async def retry_track_access(track_sid):
for attempt in range(3):
await asyncio.sleep(0.1 * (attempt + 1))
try:
publication = room.local_participant.track_publications[track_sid]
print(f"Successfully accessed track on attempt {attempt + 1}")
break
except KeyError:
if attempt == 2:
print(f"Failed to access track {track_sid} after 3 attempts")`
◦ Make sure the track is properly registered in track_publications
before you try to access it. Adding some retry logic can help handle those tricky race conditions:
1. *Handle Participant Disconnects:*`room_options = RoomInputOptions(close_on_disconnect=False)`
◦ By default, when a participant disconnects, the agent session closes. To keep it open, just set RoomInputOptions.close_on_disconnect=False
when you’re setting up the room.
1. *Keep an Eye on Events:*`@room.on("participant_disconnected")
def on_participant_disconnected(participant):
print(f"Participant {participant.identity} disconnected")`
◦ It’s helpful to listen for participant connections and disconnections so you can handle them smoothly:

08/07/2025, 12:52 PM'signal client closed: stream closed'
usually pops up when the WebSocket connection to the LiveKit signal server closes unexpectedly. No worries though—here’s a friendly guide to help you sort it out:
1. Check Network Connectivity: First, make sure your client has a steady internet connection and that the LiveKit server URL is reachable.
2. Implement Reconnection Logic: It’s a great idea to use the SDK’s built-in reconnection features or add some retry logic to handle any disconnections smoothly. Here’s an example:
async def reconnect_with_retry(max_attempts, delay):
for attempt in range(max_attempts):
if attempt > 0:
await asyncio.sleep(delay)
try:
await signal_client.restart()
print(f"Successfully reconnected after {attempt + 1} attempts")
return
except Exception as e:
print(f"Reconnection attempt {attempt + 1} failed: {e}")
3. Verify Server Configuration: Double-check that your LiveKit server URL and authentication token are both correct and valid.
4. Handle Disconnect Events: It helps to listen for disconnect events and add retry logic there too:
@signal_client.on_close
def on_signal_close(reason):
print(f"Signal client closed: {reason}")
# Implement reconnection logic
5. Monitor Server Logs: Take a peek at the LiveKit server logs for any errors or warnings that might shed light on why the connection closed.

08/07/2025, 1:02 PM32204: Invalid Caller ID
pops up because the From
number in your SIP INVITE isn’t a verified outgoing caller ID for your account. No worries though — here’s a simple way to fix it:
1. Verify Caller ID: Double-check that the number you’re using as the caller ID is verified with your SIP provider. For example, if you’re on Twilio, you can verify your number in the Console under "Verified Caller IDs."
2. Use a Valid Caller ID: Make sure the From
field in your SIP INVITE uses a number that’s either:
◦ Verified on your account
◦ Provided by your SIP trunking provider
1. Check Trunk Configuration: Confirm the number is listed in the numbers
field of your outbound trunk configuration.
2. Verify Authentication: Make sure your auth_username
and auth_password
are set up correctly for the SIP trunk.
3. Review Provider Documentation: If you’re using a specific SIP provider like Twilio, take a peek at their documentation for error code 32204
— they often have helpful tips on fixing invalid caller ID issues.
If you’re still stuck or want a hand, just share a bit about your SIP provider, the caller ID you’re using, and your trunk setup (don’t worry, no sensitive info needed!). We’re here to help!

}
}
◦ Then, create the trunk with this CLI command:
lk sip outbound create outbound-trunk.json
1. Configure the Dispatch Rule:
◦ Set up a dispatch rule so your outbound calls go to the right room or agent. Here’s an example:
{
"trunk_ids": [
"<your-trunk-id>"
],
"rule": {
"dispatch_rule_direct": {
"room_name": "<your-room-name>",
"pin": "<optional-pin>"
}
}
}
1. Initialize Outbound Calls:
◦ When you’re ready to make a call, use the CreateSIPParticipant API like this:
sip_participant = await livekit.create_sip_participant(
room_id=room_id,
participant_id="sip-participant",
phone_number="+1234567890",
sip_trunk_id=trunk_id
)
