In fact, I am not looking for "if address is NATed or not", I need to
check if address belongs to my network or not.
what do you mean by RFC1918 addresses ?
Thanks,

Why not test for RFC1918 addresses? That's what the
onsip.org
nat-handling scripts do. A NATed destination is determined by a flag in
the location record and the src ip is checked with nat_uac_test(). It
will give a more robust NAT handling that testing on IP addresses for
parts of the RFC1918 addresses.
The problem has already been solved, why not reuse? ;-)

RFC 1918 - Address Allocation for Private Internets
addresses like 10.0.0.x or 192.168.x are "private" ip addresses, they
can only exist behind NAT gateways, and cannot be connected directly to
the internet.
Is your mediaproxy inside or outside your NAT gateway?
