Re: [Users] Problem with voice

Hi Andrew,

first step will be to check on signalling level to see if SDP is correctly negotiated (IP and port). Than, try to get on the net to see if there is any RTP traffic between.

Hi

I am new to all openser related things. I managed to install it, combine with postgres and do simple accounting, but now I am facing a slightly problem. The situation looks like this:

I have two sip phones both on public IP and both registered to openser (on public IP). I am able to ring between this two phones (so I guess that the sip signalization works OK), but I can't hear any voice. For testing purposes I disabled the firewall on openser so I am sure that all ports are "free". My openser.cfg looks like this:

What could cause this silence? I was wondering maybe mediaproxy or rtpproxy could help, but there is no nat so I can find a reason why I should use them.

Could you check my conf file and point me into appropriate direction. Any kind of help would be gladly expected.

Best wishes to all.

Andrew
