Still don't think it's possible but I have to ask. Customer has Succession 3.0 and wants to be able to page over the speakers of multiple 3900 sets at the same time. I know you can do it with a Norstar or any other Key system probably but has anyone found a backdoor way to do it with the PBX? I know I can set up Dial Intercom Groups for 1 at a time or Voice Call but they want to be able to many phones at 1 time.
