Hey Tony,
Thanks for your reply. That's the whole deal, the company that sold us this unit are charging us each time they come out and make a change. Each time they come out, the system get more and more messed up.
Not only that, they didn't train any of the staff to make these what I think are simple changes. Maybe they're not.
Sometimes one just have to learn the hard way. I'm the IT person for the company and I came on board after the purchase and installation of this phone system. So I've inherited this monster. The system is much more advanced then this office's current needs. The authorized dealer sold them a Cadillac when all they needed was a Corolla.

Ideally I would like the phone to ring at the receptionist ext (200) but would like any other ext to pick up the phone as well. If after 3 ring s and no one picks up, it goes to auto-attendant.
And auto-attendant should have day mode and night mode.
At the moment no one else can pick up the line but ext 200 so I know I have to program each of the other exts to be able to pick up.
