I did more experimenting and seams the issue only exists in two of
three configurations. If I can fix the first I think it will fix the
second as well.
If both ATA ports share the same username and serial forking is used,
the issue as described below happens. Looks like the issue is that I
never called route(NATMANAGE) in the serial forking failure route.
If you are having your config based on default kamailio.cfg, then you
should engage the branch route before sending out any invite.
Cheers,

I do control, this particular setup is in my lab. I just took another
look at the captures and see both RTP streams (viewing in front of
firewall). First call rtp is sourced from Kamailio(rtpproxy) second
call rtp is sourced from one of the backend asterisk servers (which is
where the issue is, should also be from rtpproxy).

Is the firewall a system that you control and can do traces on it? Can
you see rtp coming to it? Is it forwarded?

Hello,

Can you get a SIP network trace on UA? If yes, compare it with
the one captured on server.

Setup is -
2 port ATA <> FIREWALL <> KAMAILIO / RTPPROXY <> ASTERISK
If I have a single port in use behind the firewall, all
NAT functions work properly and media is relayed through
rtpproxy.
If I have both ports in use behind the firewall, when
outbound calls from UA are placed there is two way audio
on both calls. However if inbound calls are placed to UA,
the first call works, second call only has outbound audio.
Different SIP URI is used for each port.
If the firewall is eliminated everything works fine.
Anyone have an idea how to troubleshoot or what could be
missing? I have done packet captures on both the UA side
and Kamailio side, and I see two RTP flows (rtp ports
match on both sides as well) despite lack of inbound audio
on the second call.
If I can post anything config wise that would help let me
know.
Thanks!
