Mark Murawski commented on ASTERISK-29202:
------------------------------------------
With WAN2 completely removed. I get a different error, all else being equal:
[2020-12-09 22:36:57.757] ERROR[24546]: res_pjsip.c:4361 endpt_send_request: Error 120022 'Invalid argument' sending OPTIONS request to endpoint 21005
This endpoint/contact is coming in via tun0 transport
Same thing occurs when coming in via tun1
Same things occurs when coming in via wan1 (transport-udp)

> Affects Versions: 16.15.0
> Reporter: Mark Murawski
> Assignee: Mark Murawski
> Severity: Minor

> Reasonably complex setup here, but nothing out of the ordinary. We have multiple ways to get in and out of this box, and we need to make sure Asterisk uses the right settings for the right subnet!

> Notes:
> Setting transport=transport-udp will 'work' and pjsip can successfully send SIP OPTIONS to this endpoint/contact, but if say the endpoint initiates a call to Asterisk via transport-udp-tun0, obviously asterisk will respond on the wrong transport and things will not work.
> Generic setting of having NO transport= will allow INVITEs to process from this endpoint to Asterisk properly and two way audio is successful and all that good stuff. But asterisk cannot 'reach' the endpoint, because now it considers it down
