Hi,

I have a problem, for call telephone numbers it's ok, but when I make 
call to users to make a P2P connection, I have one problem..

Look, the peer=- is empty, why ?

I connect each other, but I doesnt listen nothing, maybe because of this 
peer.

I look at wireshark, I doesn't have problem with NAT.

Thanks!
