Hi, using a UCM6204 in a large home environment.
Have a combination of wireless and desk phones and a couple of trunks.
One of the trunks is my main Analog, phone company trunk.
When a call comes in on this trunk, it is sent to a ring group and as a result most phones in the house, ring.
Whoever picks up the call, “owns it”.
But I would like other phones (well, at least one) to be able to join the call…without knowing the extension of the current call owner.
It’s kind of like a trunk version (rather than extension version) of a call barge…
