How do you get asterisk to behave like a 1A2 key system. We need to allow multiple parties to pick up a call that is in progress like on an old fashioned system where all the stations are permanently bridged. We would like the LED’s on the phones to be associated with the c/o lines and show in-use whenever the c/o line is in use. We would like a third party to be able to enter an existing call by pressing an in use line key like on 1A2. The customer finds it too confusing to transfer or park calls.
I wouldn’t swear to it, but I don’t think that Asterisk supports shared appearances. I’d like to be told I’m wrong though because I could get some use out of having a few shared extensions…
