How to make an AI agent hang up a SIP call proactively

Telephony
1

This question originally came up in our Slack community and the thread has been consolidated here for long-term reference.

We are using LiveKit for SIP calls with Exotel as our telephony provider.

We want the AI Agent to cut the call proactively when it detects the conversation is complete. We tried disconnecting the room:

self.room_ref.disconnect()

But the call keeps going and the user has to hang up manually. Our telephony provider said they didn’t receive any BYE signal from LiveKit.

How can we properly hang up the call from the agent?

2

Having the agent disconnect or leave the room does not hang up the call.

To hang up the call, you need to delete the room. This sends the proper BYE signal to the telephony provider.

See the documentation:

Hey guys,

Saw like 2 different ways for the Agent to hang up the call. Would appreciate views on which makes the most sense.

  1. session.shutdown()- seems to mimic the Participant disconnect flow best. _aclose_impl(USER_INITIATED) scheduled → drains pending speech → cleans up STT/TTS/LLM pipelines → emits “close” event → _on_close handler sets endreason (won’t overwrite, already set) → delete_room_on_close fires as it is set as True → deletes room → SIP call ends → shutdown_fut resolves → job runs shutdown callbacks → process exits
  2. delete_room (per the official docs) - when I get the agent to delete room, the room seems to get deleted twice sometimes. This one time, the STT pipeline did not end even though the room has been deleted and went on for 40 minutes after room deletion
4

Do you have logs from the agent from when this happened?

5

Hey this is my end call implementation. I realise in my code that this function was made to be called twice (You will see 2 logs below, one is room deleted successfully, one is room close failed). But anyway when that happens, STT pipenline did not seem to end without a room:
async def end_call(ctx: JobContext, session: AgentSession):
if ctx is None:
return

try:
await ctx.api.room.delete_room(
api.DeleteRoomRequest(
room=ctx.room.name,
)
)
logger.info(“room deleted successfully, ending call”)
except Exception as exc:
logger.warning(f"room close failed: {exc}")

I see these logs when this function is called as a tool (using deepgram which returns STT metrics every 5 sec):
