[OpenSIPS-Users] Minimal example of NAT traversing. How could it be done? No need for MediaProxy at first glance.

[Bogdan-Andrei Iancu]

Rodrigo,

In OpenSIPS you have 2 type of NAT modules:
- for NAT detection, mangling SIP signaling and for doing the NAT 
keepalive: you have here the NAT_traversal and nathelper, 2 similar 
modules as capabilities;
- for media relay - modules that interact with an external media relay 
for RTP; and here you have again 2 modules, the mediaproxy and rtpproxy.
