Hi,
I search for Kamailio source, and found that Kamailio doesnot handle the
x-NAT field in SDP body.
When client use STUN, it can detect the NAT type. When client register, it
contains x-NAT (0:unknown, 1: full cone, ..., 6: symmetric), which will be
helpful for the server to detect NAT type.
Why doesn't Kamailio handle x-NAT? I think this is a must-have feature
