Subject: SIP Inbound Trunk returns 404 despite correct configuration

Project: jbsync-voice-agent-096ubv05.livekit.cloud

Trunk ID: ST_FkJ9r9HuzUyE

Numbers: +3197010208583

Failed call: 2026-04-10T13:31:38Z

SIP INVITE To: sip:+3197010208583@jbsync-voice-agent-096ubv05.sip.livekit.cloud;transport=tcp

Issue: Twilio sends SIP INVITE, LiveKit returns “404 No trunk found”. Trunk has matching numbers, allowed_addresses includes 0.0.0.0/0, dispatch rule exists. Worker is registered. No room is created, worker never sees the call.

Twilio support confirmed the 404 comes from LiveKit’s side (ticket #26125899).

Do you have the call-id for that call?

But just looking at what you posted this looks quite wrong:

>SIP INVITE To: sip:+3197010208583@jbsync-voice-agent-096ubv05.sip.livekit.cloud;transport=tcp

That should return a 404 because it is not a valid SIP URI.

You need ot use your SIP URI for SIP calls which you can find here Sign in | LiveKit Cloud
