I made the outbound call agent within Livekit and Twilio. But the ringing from agent is not existed when run the agent and user with phone number.

It seems like the issue might be related to the SIP participant's call status or the configuration of the SIP trunk. According to the LiveKit SIP documentation, when making outbound calls, the

sip.callStatus

attribute should change to

active

once the call is picked up. If the ringing is not heard, it could be due to the SIP participant not being properly connected or the audio track not being published. Ensure that your SIP trunk is correctly configured and that the

play_dialtone

option is set to

true

in your

CreateSIPParticipant

request to play a dial tone while the call is dialing. Here's an example configuration:

{
  "sip_trunk_id": "<your-trunk-id>",
  "sip_call_to": "<phone-number-to-dial>",
  "room_name": "my-sip-room",
  "participant_identity": "sip-test",
  "participant_name": "Test Caller",
  "play_dialtone": true
}
