Ok i will check the flags, I set the domain parameter of rtpproxy_offer to PUBLIC_IP, i create the rules in my router to bind the ports 35000 to 35200 of the public_ip to the ports 35000 to 35200 in the PRIVATE_IP of rtpproxy 192.168.1.220, I'm not sure if this is correct.<br>
<br>If i don't put the domain parameter in the rtpproxy_offer the SDP message contains the private ip of the RTPPROXY (192.168.1.220) and my clients are outside this nat.<br><br>Thanks<br><div class="gmail_extra"><br>

<div><tt>Hi, Ignacio!<br>
<br>
The ports you have listed in the SDP snippet belong to a single
rtp stream - Callee-RTPProxy-Caller. You should also check the
ports in the 200OK.<br>
The "nortpproxy_str" parameter you are specifying is used by
RTPProxy to determine if the SDP has to be changed, or somebody
else already changed in the path.<br>
I noticed that you call rtpproxy_offer() function with two
parameters:<br>
1. "ro" - if the SDP has a private IP, you shouldn't use the "r"
flag. This flag is used to specify that RTPProxy should accept
packages only from that IP, whereas in your case he will receive
the packets from a public IP.<br>
2. "domain" - you shouldn't use this parameter unless you really
know what you are doing. This overwrites the domain specified by
RTPProxy, which is not always such a good idea.<br>
<br>
I hope these remarks will help you fix your problem.<br>
<br>
Regards,<br>

But there is no audio, i check the traffic using wireshark and i
see that a lot of packets are sent to another port not the one
that i send in the first message, example:<br>
<br>
First SDP<br>
<br>
v=0<br>
o=- 465641 0 IN IP4 10.168.123.201<br>
s=-<br>
c=IN IP4 10.168.123.201<br>
t=0 0<br>
m=audio 11670 RTP/AVP 0<br>
a=rtpmap:0 PCMU/8000<br>
a=sendrecv<br>
<br>
<br>
<br>
Changed by opensips and rtpproxy to look like<br>
<br>
<br>
v=0<br>
o=- 465641 0 IN IP4 IP_PUBLIC<br>
s=-<br>
c=IN IP4 IP_PUBLIC<br>
t=0 0<br>
m=audio 35000 RTP/AVP 0<br>
a=rtpmap:0 PCMU/8000<br>
a=sendrecv<br>
<br>
<br>
And packets are being recived on the udp:<a href="http://10.168.123.201:45708" target="_blank">10.168.123.201:45708</a><br>
<br>

Thanks for your help<br>

Hello, I change the command line to run rtpproxy and change
my configuration file:<br>
<br>
./rtpproxy -l <a href="http://timewarnercable.dyndns.org" target="_blank">timewarnercable.dyndns.org</a>
-s udp:<a href="http://192.168.1.220:12333" target="_blank">192.168.1.220:12333</a>
-n tcp:<a href="http://192.168.1.220:12333" target="_blank">192.168.1.220:12333</a>

<br>
rtpproxy_offer("ro" , "<a href="http://timewarnercable.dyndns.org" target="_blank">timewarnercable.dyndns.org</a>");<br>

And now the SDP message looks like this:<br>

a=rtpmap:0 PCMU/8000<br>

a=nortpproxy:yes<br>

But there is no audio, and I don't know what is the meaning
of the a=nortpproxy:yes<br>
