Do you have any idea how fucking insane the h.323 protocol is?  Anyone
 who runs a h.323 should get shoved out a window, beaten, flayed,
 spanked, shot, disembowled, hung, and forced to listen to hummpa music.  If
 you  want to firewall h.323, go commit yourself to an asylum with
 straight jackets and with padded walls -- at least you'll be in common
 company with the other linux wacko's.
