Hi Muzaffar, Net2phone doesn't use H.323. I don't know what the exact protocols are, but I believe it requires secondary connections. You can make it work if you install the firewall client and create an "all IP traffic" rule, but that's not too secure :-) You can harass the net2phone devs and ask them what the primary and secondary connections are.
