Parking a call is an alternative to holding a call. A call parked on the telephone system can be retrieved by any other user if they know the system park slot number used to park the call. When the call is retrieved, the action is known as Ride Call.
Each parked call requires a park slot number. Attempting to park a call into a park slot that is already occupied causes an intercept tone to be played.
The Park Timeout setting in the IP Office configuration (System | Telephony | Park Timeout) controls how long a call can be left parked before it recalls to the user that parked it. Note that the recall only occurs if the user has no other connected call.
There are several different methods by which calls can be parked and unparked. These are:
Using Short Codes
The short code features, ParkCall and UnparkCall, can be used to create short codes to park and unpark calls respectively. The default short codes that use these features are:
Using the Phone Manager and SoftConsole Applications
The Phone Manager and SoftConsole applications all support park buttons. Clicking on these allows the user to park or unpark calls in the park slot associated with each button.
In addition, when a call is parked in one of those slots by another user, the application user can see details of the call and can unpark it at their extension.
By default the application park buttons are associated with park slots 1 upwards. However these park buttons can be reconfigured to match different park slot numbers.
Using DSS Keys
The Park feature can be used to associate a DSS button on a telephone with a particular park slot number. The DSS button can then be used to park and unpark calls from that park slot. The DSS buttons BLF lamps will indicate when a call is parked in the associated park slot.
Some telephones support facilities to park and unpark calls through their display menu options (refer to the appropriate telephone user guide). In this case parked calls are automatically put into park slots matching the extension number. For example, the first call parked by extension 201 would go into park slot 2010, the next into park slot 2011 and so on.
