[Serusers] rtpproxy for private networks without NAT and way outside

[Gregory Sandul]

Thanks you Jan, and thanks to Klaus.
I've used in my config

Now SIP signaling messages work fine.
But in the SDP body RTP IP address is not fixed,
probably I need to use textopts.so module to fix SDP?

Regards,
Greg.
