Hello everyone,
there are plentiful discussions on this topic here, but I can’t seem to find anything that resembles my situation.
Outbound route works with Twilio (FreePBX 14).
Separate outbound routes have been created for all 4 IPs with the following User Details for Incoming Tab:
However upon attempting a call, on the Twilio side I see Authentication error 401, on FreePBX side the following line:
NOTICE[24262]: res_pjsip/pjsip_distributor.c:649 log_failed_request: Request ‘INVITE’ from ‘“Unavailable” sip:[email protected]’ failed for ‘54.171.127.193:5060’ (callid: 2[email protected]) - No matching endpoint found.
I have spent several days looking for solution and trying various configuration options, but still unsuccessfully.
You appear to have created chan_sip trunks, but your inbound calls are arriving on the pjsip port. Adjust the port to which Twilio sends calls to match your chan_sip port.
… or better yet, set up PJ-SIP trunks for these. We’ve talked quite a bit about Twilio trunking in the past and the consensus seems to be that Twilio works well with PJ-SIP.
You can have PJ-SIP and Chan-SIP trunks with all the same information, so you can do this as a test and make sure it’s going to do what you need.
Thank you @lgaetz, @cynjut and @sorvani very much for your suggestions!
I ended up creating Twilio chan_pjsip trunk that serves for both outgoing and incoming calls, and it works now in both directions flawlessly.
Since it was my second FreePBX setup at first I decided to go for plain chan_pjsip driver for both trunks and extensions, but my 12 trunks sporadically were loosing registration. Therefore I built all my trunks as chan_sip that proved to be much more stable. My extensions are still remaining on chan_pjsip driver. Both receiving and initiating calls works well for all my trunks, and only chan_sip Twilio inbound failed.
