I can see where a NAT proxey server will know the true
ip address of a client and do appropriate translations
of IP addresses in SIP headers. However once SIP is
done and voice is transmitted point to point with RTP
how do the RTP packets get through the NATs? (unless
port forwarding has been configured on the NAT which
from what I can tell it hasn't)

New subject: [Serusers] There is something about NAT and VoIP I don't understand.
If no end-to-end communication is possible then SER rewrites the IP in
SDP with the IP of RTP proxy that will relay all the media traffic.
