[Leon Li]

Thanks Razvan for your reply,

 

Could you kindly instruct me how to turn on debug level for rtpproxy?

 

Regards,

Leon

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".

In the debug on calls from EP2 to EP1, I got

Mar 24 00:06:02 [24298] DBG:nathelper:force_rtp_proxy_body: proxy reply: 48126

 

Can anyone shed some lights on what could be wrong?

 

Thanks,

Leon
