Hello!<br><br>I&#39;m using SER + rtpproxy, but altough the NAT problem seems to be solved, I get no audio ... analysing the traffic with ethereal, I realized that the traffic going from the proxy to the UAs never arrives&nbsp; (ICMP unreacheable destination)... I assume it is because the users have their ports blocked, is that correct? I changed the&nbsp; rtpproxy port range (PORT_MIN and PORT_MAX ) to lower ports, but still I got the same messages...
<br><br>Does anybody knows anything that can be done by me in terms of configurations of the rtpproxy or ser.cfg or whatever, given the fact that I don&#39;t have power to open the ports??.....<br><br>Thanks,<br>Amanda<br clear="all">
