Purchasing Agent commented on ASTERISK-27892:
---------------------------------------------

There is no errors generated in cli> or log files.
We've done a lot of digging to show rtp is using ipv4 when connected to ipv6 endpoint.

Make a call, no audio. Not sure what else you want to see,.

> When endpoint uses IPv6, rtp is incorrectly binding to ipv4 port instead of ipv6 port on PBX.
> For debugging, added rtp_ipv6=yes to one extension in /etc/asterisk/pjsip.endpoints.conf and restarted asterisk
> the endpoint now shows:
>  rtp_ipv6                           : true
> Logging of a call from the router in front of PBX shows:
> 15:39:57 firewall,info FROMPHONE forward: in:br-management out:ether2, src-mac 00:18:74:27:82:40, proto UDP, [2607:fea8:20df:fc31:
> 20b:82ff:fe95:223a]:5012->[2607:f938:1001::b154:4edb]:16376, len 190
> netstat -tupan shows the port 16376 is udp4 and not udp6
> udp        0      0 xxx.193.49.61:16376     0.0.0.0:*
