Parking a call is similar to holding a call. However, parked calls can be unparked by other users on the phone system.
Each parked call is given a number. By default, the number is your extension number plus a digit.
Calls that you park return to your phone (when idle) if they remain parked for too long. The default return delay is five minutes. This is a system delay that is applied to all users and can be changed by the system administrator. Returning calls ignore any forwarding or do not disturb settings.
A feature button set to the Call Park action can be used to park and unpark calls and to indicate parked calls.
