Hi Max,<br>
<br>
Thanks for your reply.<br>
<br>
I have rtpproxy running and I think it's all configured ok.<br>
<br>
I can use fix_nated_sdp() with flags and see the changes in the sdp
lines in the packets.<br>
<br>
What I am struggling with is just how to go about telling the asterisk
server and the outbound route that all traffic is to run through my
proxy<br>
<br>
I'm not sure what the purpose of the o= and c= lines are and at which
stage in the packet flow I need to re-write which lines.<br>
<br>
If anyone can offer any pointers that will be awesome.<br>
<br>
Kind regards,<br>
John<br>

<pre wrap=""> Hello,
Yes, the opensips will rewrite the sdp like you said, so it will contain
the ip of the rtpproxy (or mediaproxy). It can be used to proxy the rtp
traffic to a specific destination.
But the rtpproxy does not necessarily have to be the same machine as
your Opensips. The rtpproxy is a different tool which will be enabled by
setting the relevant modparam settings and also calling the rtpproxy in
your routing-script.

maybe there are also other, better tutorials but this link seems to be a
good start for setting up rtpproxy with opensips.

<pre wrap="">Hi,
I have a setup as follows:
1.2.3.4 - Outbound Route
4.5.6.7 - Opensips proxy
4.5.6.8 - Asterisk server
The outbound route will only allow any traffic, signaling and media, via
the 4.5.6.7 IP address. It cannot currently accept media from a
different ip than the signaling.
Currently the astx server sends media direct to the outbound route.
Signaling is fine but I need to force the media stream from the asterisk
server through the opensips proxy.
Am I correct in expecting that nathelper/rtpproxy can do this?
Is it simply a matter of re-writing the sdp detail that will tell the
asterisk server to route media through the opensips ip address?
Any examples will be greatly appreciated.
Thanks,
John
