Joshua C. Colp commented on ASTERISK-30356:
-------------------------------------------

The rewrite_contact option has no affect on audio. The rtp_symmetric option sends audio to where it is received from. There is also no "outbound connection". I'd suggest seeking help on the community forum first[1] with logs and information, after which if an issue is determined then this can be reopened.

> I suspect asterisk and/or pjsip is not rewriting the contact header with source ip address and port when using the rewrite_contact option in ps_endpoints.
> I have used this option in the past with success, when address is an internal nat'd 192.168 address.  Recently, using soft phone on cellular data network, i have seen ipv6 ip addresses show up in the sip headers while the source address is indeed ipv4.
> SIP packets move back and forth but when answering a call, no audio is passed and asterisk console shows this:
> WARNING[4801] acl.c: Cannot connect to 2605:b100:349:5cd1:0:4:375a:3e01: Cannot assign requested address
> it looks like the outbound connection is trying to go to an ipv6 address instead of the source ipv4 address.
