I have a problem when communicating to an Avaya Communication Manager PBX, it seems to fail if the Allow-Events header is present. I've reported this as a bug to Avaya, but I just wanted to make sure if it's in any way possible to stop FS from sending this? I understand if it's not, since this is really an Avaya problem - but I just wanted to make sure, before I start poking around in the code.. :) /Peter
