Here's the situation. We have two users with M2616 phones. The PBX is opt11c (or successession 3.0 these days i guess). At present they each have their own extension (very basic setup).
Phone1: 3648
Phone2: 3675
Both phones are also configured to forward to other extensions on busy/no-answer (3648 -> 7721, 3675 -> 7775).
What they want to happen is when a call comes into the system for 3675 then both phones should ring. If both phones are busy or no-answer then the call goes to 7775. At the same time calls to 3648 should continue to work exactly as they do now.
Thoughts?
