Call Pickup is a useful function. This allows other users to pickup calls from their desk without running across the office or room to pickup a colleagues phone. These calls may be direct in-dial calls, or a call that has been transferred to the phone from another extension or from the receptionist.

Each extension can be set to a particular call group or one office wide call group. What this means is that if you want only the accounts department to pick up calls in the accounts departmen, they can be set as one call group, and sales set up as another account group. This way the sales department cannot accidentally pickup an accounts call.
