Dear OpenSIPS-users.
The function nat_uac_test() (from module NATHELPER) works very well and tells me whether a cliente to my OpenSIPS is behind a NAT. But, for my specific network topology, is my OpenSIPS that is behind a NAT, from the client perspective. In this case I have to fix the SDP content that goes from OpenSIPS to the client, so that the client will be able to send its media to a public IP, when communicating to a peer in the same network domain of this SIP server. How can I be sure that for a client perspective the OpenSIPS is behind a NAT? In another words, is there a way to the OpenSIPS determine if its client is in the same network or in a remote network? -------------- P.S. I suspect that OpenSIPS should be used in a node with public IP to simplify our solution. But our customer asked us to put OpenSIPS in a residential device that will be always behind a NAT for some smartphones perspective and not behind a NAT for another home devices perspective. --------------- Any hint will be very helpful!
