"Temporarily Unavailable" when 3-way calling
Can someone help me with the concept of 3-way calling with the "Invite" button? After establishing an initial 2-way call (even just between internal extensions), when I attempt to add another party to the call, the slot where the number sits says "Temporarily Unavailable" in red. I have a suspicion it has to do with my SIP server or how I've configured this SIP extension.
I've attached a picture of the cp960 screen when this happens.
