[Kamailio-Users] Engaging rtpproxy

[Graham Wooden]

Sorry for the late reply; things have just been way hectic and haven't had
time to circle back around on this.

Klaus, what would be the best way to call force_rtp_proxy() in the
reply_route section?  As mentioned prior, I don't want to handle the audio
for all calls.  Do I need to set a flag or something?
I have rtpproxy installed and kamailio sees it (via the sock).
I am doing the force_rtp_propxy in the 302 statement...

What is occuring now is the call goes back out to the PSTN but there is no
audio....

Any guidance is much appreciated.
