I'm asking you if is possible to let asterisk send some packets (even fake ones or the real CNG fax tone) from the declared SDP port to the outside world. This will open the NAT hole that rtpproxy need to permit to all this situation to work correctly. This will avoid to have NAT mapping and so on in the customers router/firewall.
