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?
You have 2 possibilities:
- use the same reply route for all transaction and mark the
"rtpproxy-ing" transaction with a flag
- activate the reply-route with force_rtp_proxy only for those
transcation which need it. Further, put a "cockie" (a record-route)
parameter) for this transaction into the record router header, .e.g
nat=yes. Then, when doing losse_route for in-dialog requests check for
the existence of the parameter (see README of rr module) and if nat=yes,
then call force_rtp_proxy and active the corresponding reply router.
in the reply route call force_rtp_proxy if reply code is 180 or 183 or 200.

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.

Hi!
Note: There are 2 RTP proxies for Kamailio:
for Kamailio <= 1.3: rtpproxy (controlled via nathelper module) and
mediaproxy (controlled via mediaproxy module)
for Kamailio >= 1.4: rtpproxy (controlled via nathelper module) and
mediaproxy2 (controlled via mediaproxy module)
mediaproxy2 is a Linux kernel module and I think you can not record with
it. AFAIK rtpproxy supports recording of sessions.
http://www.kamailio.org/docs/modules/devel/nathelper.html#id2506972
3xx can be caught in failure_route.
There you execute get_redirects("*"); the force_rtpproxy and then
t_relay. Further make sure that force_rtp_proxy() is also called for the
200 OK response (reply route) and furter in-dialog requests.
