call.in-progress.error-sip-outbound-call-failed-to-connect
Hello Vapi team 
I’m currently trying to connect my on-premise Asterisk server with Vapi using a SIP trunk and a BYO phone number.
What I'm trying to achieve:
When someone calls my GSM line (connected via a GOIP gateway), the call should be received by Asterisk and then forwarded to a Vapi assistant.
I've attached two files:
sip_traffic.pcap – a SIP traffic capture recorded during a failed call.
vapi_asterisk_conf.txt – the relevant parts of my pjsip.conf and extensions.conf.
Current issue:
The call reaches Vapi and appears in the Call Logs as "Queued",
But then fails shortly after with the error:
call.in-progress.error-sip-outbound-call-failed-to-connect
The assistant doesn't speak, and the call disconnects within 1 second.
I would appreciate any help or insights — especially if you can review the SIP traffic and see what's wrong in the dialplan or signaling.
Thanks in advance!
