[Kamailio-Users] How to know if a UAC is behind NAT after fix_nated_register() ?

[Pascal Maugeri]

Hi

A quick question, when I apply a fix_nated_register() to a remote user when
he/she registers, how can I know later on if this user is behind NAT ?

All my calls go through a B2BUA:

Caller ------> kamailio/rtpproxy ------> B2BUA ------> kamailio/rtpproxy
------> Callee

When my B2BUA calls a user, I want to know if this user is behind NAT or
not. For now all the calls go through rtpproxy but I would like to apply
this path only when user is behind NAT.

Regards,
Pascal
