[Serusers] Hairpin solutions?

[Greger V. Teigre]

Also, many NATs can handle hairpin media quite well. I think there is an RFC 
with a list of tested NATs.  Another suggested solution is to test caller's 
and callee's public IPs and not force proxy if they match (you need to know 
that the internal NAT is routable and non-NATed for this to work).
