<div><tt>Hi, Ignacio!<br>
<br>
So you are trying to use RTPProxy in bridge mode (between a
private and a public network). This means that for INVITE you
should have a public IP, and for 200OK a private IP (or the
other way around, depending on your scenario). You have three
possible solutions to achieve this:<br>
<br>
1. For INVITE, call rtpproxy_offer("flags", "PUBLIC_IP") and for
200OK, rtpproxy_answer("flags", "PRIVATE_IP") (or reverse the
IPs in case of a different scenario). I am not sure this works,
as RTPProxy will have no idea about where exactly is your
UAC/UAS - therefore it might use wrong sockets to send data (for
example, it might use a PRIVATE_IP socket to send RTP to a
public ip).<br>
2. Enable the autobridge mode, by setting the
'rtpproxy_autobrige' parameter [1]. I've never used this, so I
can't confirm whether it works properly or not.<br>
3. Call the rtpproxy_offer/answer functions with the 'E' or 'I'
flags[2]. This is the most reliable method I've used I can
confirm it works.<br>

If i don't put the domain parameter in the rtpproxy_offer the SDP

<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>
