When you park a call, anyone who knows the slot number can pick up the call.
Procedure
To pick up a parked call, do one of the following:
Dial the default short code *38*N# where N is the park slot number.
If console users have a park slot button set to the same park slot number, the button indicates the parked call. They can click the button to unpark the call.
On Avaya telephones with programmable buttons, users can program buttons to match particular park slot numbers. The button indicates when a call is parked in that park slot and can be pressed to unpark the call.
