We setup a sip trunk through a MBG to a 3300. Everything works, but all incoming calls use double the licenses. Eg, one incoming calls shows 2 licenses used. Mitel says the reason is the the SIP provider is sending the option supporting FAX on the sip trunk, so the MBG is using a sip license for voice and one for fax, even if its just a voice call.
Anyone know how to stop it?
