I removed it and I still have the same problem. My onreply_route looks like
this now.
onreply_route[1] {
if (status =~ "(183)|2[0-9][0-9]") {
fix_nated_contact();
force_rtp_proxy();
} else if (nat_uac_test("1")) {
fix_nated_contact();
};
}
I also tried this..
onreply_route[1] {
fix_nated_contact();
force_rtp_proxy();
}
I must admit that I'm new to all this SIP routing. :(
One more thing of note is that we are getting the following errors in the
syslog.
Feb 17 12:53:15 lvl3 /usr/local/sbin/ser[19711]: ERROR: send_rtpp_command:
can't read reply from a RTP proxy
Feb 17 12:53:29 lvl3 /usr/local/sbin/ser[19716]: ERROR: extract_body:

Feb 17 12:53:29 lvl3 /usr/local/sbin/ser[19716]: ERROR: force_rtp_proxy:
can't extract body from the message
Feb 17 12:53:29 lvl3 /usr/local/sbin/ser[19716]: ERROR: on_reply processing
failed
I just noticed this on my last call attempt.
Any more suggestions. I've tried all kinds of combinations .. I'm stumped..
Thanks!

Subject: Re: [Serusers] RTP Proxy Help - One way Audio
As I said in my previoud message, most likely that
isflagset(6) test in
onreply_route is causing problems. Remove it completely and try again.

I am using the default nathelper module config, but I have hacked it a
bit and maybe my changes are causing the problem? I had to use
t_relay_to_tcp for our PSTN gateway and so I had to change the routing
around a little.
Prior to today I was using SerMediaProxy (AG Projects), but I switched
to PortaOnes rtpproxy just to make sure that there wasn't a version
incompatibility problem.
I have also attached my current ser.cfg file.
Anyone have any suggestions? Or should I change the routing in my
ser.cfg file? or would that make a difference?
Any help would be greatly appreciated. Thanks!
