FreePBX is sending calls from a normal SIP trunk straight out to a Vapi SIP URI, e.g.:
Dial(PJSIP/vapi_trunk/sip:username@sip.vapi.ai,60)
SIP side is fine: call is answered, bridged, stays up 10–20 seconds, CDR shows ANSWERED, both legs ulaw/alaw, PJSIP trunks have Direct Media = No, Rewrite Contact/RTP Symmetric/Force rport = Yes. Oracle + OS firewalls have UDP 5060 and 10000–20000 open, Asterisk SIP Settings has the correct external IP and local network.
From the caller’s side I got absolutely nothing audio wise. no voice from the Vapi side, even though logs look totally normal.
Anyone running FreePBX and Vapi that could help me out? I would appereciate it.
