I have physical interfaces for the transports and some aliased. Here you go:
You could simulate with multiple nic's on a vm to replication my setup

> 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
