[Users] detecting if both caller and callee are behind NAT

[Bogdan-Andrei Iancu]

Hi,

this is a topic largely discussed in the past - a google on the archive 
will give you a lot of info.
shortly, you have to you avp_check() to compare the src_ip of the INVITE 
with the destination of it (dst_uri). See the avpops and the pseudo 
variables docs.

regards,
bogdan
