Hi Daniel,
I can confirm that rtpproxy_manage is called. See:
http://pastebin.com/ZVXjK9ry
I'm seeing ERROR: rtpproxy [rtpproxy.c:2260]: incorrect port 0 in reply from
rtp proxy in the logs when processing the 200OK in the re-INVITE. I've
included a debug level log from rtpproxy in the log as well.
When handling the re-INVITE there is:
• Aug 30 22:38:59 sip /usr/sbin/kamailio[25778]: ERROR: *** cfgtrace:
c=[/etc/kamailio/kamailio.cfg] l=471 a=25 n=rtpproxy_manage

but the 200OK:

I'm not familiar with the rtpproxy commands to know why it cannot locate the
session.
Thanks for your assistance,
Spencer
