Sorry - I am not sure what you are meaning by 1fl's.

I will guess at something - if wrong just ignore this.

You have a group of people that all need to answer one DID number on a PRI. But you want to put a call on hold and have another phone pick it up. Then use the SWCA (System Wide Call Appearance). That turns a PRI Target line into a Combo of Park and Hold.
Put Target line xxx to show on all phones (any number of appearances as you need). Then make a number of SWCA buttons. They will be labeled Call 1, Call 2 - etc...
Call rings in on DID Number, all phones ring. First one grabs line and it is for Sally. Push Call 1 button.
Now you can Page, Yell, Intercom, or Voice Call. Sally you have a call on Park 1 (or whatever you want to call it).


If CON is the opposite of PRO
Then what is the opposite of Progress?
