[Kamailio-Users] NAT traversal

[Alex Balashov]

I wouldn't use STUN.  It's an unnecessary complicated science project.

Unless the two media endpoints can't reach other, or the signaling 
agents can't reach other due to asymmetric signaling or bad NAT devices 
or stupidly implemented SIP ALGs or whatever, "nathelper" alone will do 
just fine.  Just apply its fixups to your Contact URIs and SDP endpoints 
and get perfectly good far-end NAT traversal.

I have deployed this many times for service providers and it works 
great.   There will always be problems with some flaky end-user 
equipment, but in general the benefits far outweigh the costs of 
screwing around with STUN or anything of the sort.
