Shared Line Appearance. Is there any way to put the same extension on 5 (say Yealink T46G) phones that would work like the old key systems did. In other words each phone would have it’s own extension but it would also have another extension that is the same. Say extension 200 was on allowed to be on 5 phones, each of the other phones would have it’s own extension say, 201-205. Whevnever the 200 was called the phones would right and indicicate an incoming call, any phone picked up that extension. The phone that answered the call could put on hold and all the phones would indicate that 200 was onhold and could be picked up by any of the 5 phones….shared like appearance. TIA.
