[OpenSIPS-Users] udp or tcp for nat traversal?

Wed Oct 15 16:31:41 CEST 2014

Hi, Bogdan:

The following is the tcpdump with mediaproxy on.
I can't see any problem. That means it is linphone problem which can't understand ice?
Actually as I said before, if I use tcp/tls, ice actually works on linphone.  
What should I do more to test it?
