Hello Leon,
As you can see, OpenSIPS receives an invalid port from RTPProxy, so the
problem seems to be there. Can you please set a lower debug level for
RTPProxy and paste me the log for this call?
Regards,
Razvan

Hello all,
I've got a problem of one way voice when making a call from a public
side to private side, where the callee on private side can't hear
caller from public side. However, if the call is initialled from
private side, everything is fine.
Here is my topology.
EP1 (public IP) à Cisco CUCM (public IP) à OpenSIPs (public IP with
rtpproxy) ß Home router (NATed) ß EP2 (private IP).
After enabled the debug as below, I found when EP1 calls EP2,
nathelper request a rtpproxy port but received an "0".

Can anyone shed some lights on what could be wrong?
