Sounds very strange indeed. If both UAs start sending RTP and you can
see that, there should be no problem (unless you have a firewall on
your rtpproxy server).<br>
<br>
Remote rtpproxy: Read the nathelper module README, you configure the
use of UDP transport for control messages instead of socket in your
ser.cfg.<br>

<div>Hi all:</div>
<div> The document metion that "RTPproxy will not be installed on
the SER server, but on a remote machine." If I install SER on "<a
href="http://192.168.1.3">192.168.1.3</a>", and install RTPproxy on "
<a href="http://192.168.1.5">192.168.1.5</a>". How do they work?</div>
<div> </div>
<div> Now, I install they on a same machine, and I run SER first,
then usr command "rtpproxy -l xxx.xxx.xxx.xxx" to force rtpproxy. The
SIP client can register behind NAT, but there are some problem with RTP
stream. I found that RTP strem is able to relay to this machine, but
this machine do not transmit those data to destination!! </div>
<div> </div>
<div>
</div>
<div> PC(A)
Server(SER+RTPproxy) PC(B)</div>
<div> RTP
Stream(A) RTP Stream(B)</div>
<div>1. ----------------------------> <----------------------------
</div>
<div> </div>
<div>2. Receive RTP stream A
and B</div>
<div> </div>
<div>3. Server should transmit RTP stream(A) to PC(B) and RTP
stream(B) to PC(A), but this step do not work. (I am not sure that
server does not forward the RTP packets or Clients do not receive RTP
packet.)</div>
<div> </div>
<div> </div>
<div> What is the problem? How should I operate if RTPproxy
install on another machine? Because the command "rtpproxy" will not be
used on the machine which have installed SER.</div>
<div> </div>
<div> Please help me, thank you.</div>
<div> </div>
