+ H.323 is a VoIP signalling protocol from ITU-T. As one of the most
+ important VoIP protocols, it is widely used by voice hardware and
+ software including voice gateways, IP phones, Netmeeting, OpenPhone,
+ Gnomemeeting, etc.
+
+ With this module you can support H.323 on a connection tracking/NAT
+ firewall.
+
+ This module supports RAS, Fast Start, H.245 Tunnelling, Call
+ Forwarding, RTP/RTCP and T.120 based audio, video, fax, chat,
+ whiteboard, file transfer, etc. For more information, please
+ visit http://nath323.sourceforge.net/.
