[Serusers] Multiple UA behind NAT and SIP Proxy Outside LAN

[Allan]

I am also looking for a way to determine if two UAs
are behind the same NAT.  I have found that if I do
not force rtp_proxy between two UAs known to be behind
the same NAT, the call is setup and torn down through
SER and RTP is sent directly between the two UAs. 
This is how I want to call to operate.  I just can't
see a way via SER's scripting language to make a
decision based on the src_ip of the initial request
and a portion of the URI domain, which in my case is
the IP address of the NAT.

Regards,
Allan
