I'm currently trying this over 2 NATs against eachother (yes, the worst case....) with some ports forwarded but with rare success. One of those NAT's rewrites a port numbers for some reason (i see the ATA registered on port 50xxx or so, the same for rtp. I think t38pt_usertpsource is meant for such a case...? [asterisk 1.6]-LAN-[NAT gateway]----inet-----[NAT gateway]-LAN-[ATA]-[FAX] Has anybody some positive experience with this? Any idea why NAT messes up the port numbers?
