[SR-Users] Kamailio with asterisk on private lan

[Daniel-Constantin Mierla]

To clarify and avoid misleading, rtpproxy should be able to do the same
as rtpengine for this case

Both modules allow to set the public IP address, by providing it as the
second parameter to rtp relay manage function. Also, the applications
themselves have parameters to specify the address to advertise.

Cheers,
Daniel
