Hi, Ignacio!
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.
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.
I noticed that you call rtpproxy_offer() function with two parameters:
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.
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.
I hope these remarks will help you fix your problem.

I change the attribute using adding this to the opensips configuration
file
modparam("rtpproxy", "nortpproxy_str", "a=sdpmangled:yes\r\n")
a=nortpproxy:yes
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:
First SDP
v=0
o=- 465641 0 IN IP4 10.168.123.201
s=-
c=IN IP4 10.168.123.201
t=0 0
m=audio 11670 RTP/AVP 0
a=rtpmap:0 PCMU/8000
a=sendrecv
Changed by opensips and rtpproxy to look like
v=0
o=- 465641 0 IN IP4 IP_PUBLIC
s=-
c=IN IP4 IP_PUBLIC
t=0 0
m=audio 35000 RTP/AVP 0
a=rtpmap:0 PCMU/8000
a=sendrecv
And packets are being recived on the udp:10.168.123.201:45708
<http://10.168.123.201:45708>
Thanks for your help

Hello, I change the command line to run rtpproxy and change my
configuration file:
./rtpproxy -l timewarnercable.dyndns.org
<http://timewarnercable.dyndns.org> -s udp:192.168.1.220:12333
<http://192.168.1.220:12333> -n tcp:192.168.1.220:12333
<http://192.168.1.220:12333> -u syrium -m 35000 -M 35200
rtpproxy_offer("ro" , "timewarnercable.dyndns.org
<http://timewarnercable.dyndns.org>");
And now the SDP message looks like this:
v=0
o=- 0 0 IN IP4 PUBLICIP
s=-
c=IN IP4 PUBLICIP
t=0 0
m=audio 35134 RTP/AVP 0
a=rtpmap:0 PCMU/8000
a=sendrecv
a=nortpproxy:yes
But there is no audio, and I don't know what is the meaning of the
a=nortpproxy:yes
Thanks for your help.

I use the same port but tcp because in the post the answer is
that. I Attach the debug file
2012/11/12 spady <[email protected] <mailto:[email protected]>>
Please, post entire opensips log ( set debug to 6 ).
Why are you using same port for sock and notify_sock ???
Have you tried with
different ports?
Bye
