The problem is that if you have two separate groups, calls for either group could come in on any channel of the PRi.

If the support people ONLY took support calls, you could have a console that showed those extensions and you would know how many of the staff were on the phones.

If you program line appearances for all channels, you should see them light up, you just would not know which channel was being used for support.
