Actually, the "correct" place to do this is at the Internet service provider.
They don't need a static IP if the ISP can somehow make known the ipaddress to
location mapping. The IP address for the destination of the audio should then
be passed along in the SIP (or whatever) messages. Problems: protocol interworking,
proxying, hairpinning, tunneling can make it so that the true IP address is
difficult to know.
