[SR-Users] how to use fix_nated_sdp("2") with multiple media types

[Daniel-Constantin Mierla]

Hello,

the signaling shows traffic going from public IP (caller) to private IP 
(kamailio) then back to public IP (callee). So it is a bit of complex 
routing if you keep it like this. The best is to get it done working 
with kamailio, rtpproxy and mcu on their public ip, because they have 
such already. Then you can think of moving to use some private networks.

Your fourth bullet below is not clear for me: the clients should have 
visibility to sip server in order to register and call, but you say not, 
maybe just a typo.

Also, I would recommend to start with latest kamailio 3.3.1 version, 
3.2.0 is very old, if you really want that release series, the use 
latest 3.2.x, not 3.2.0.

Cheers,
Daniel
