5.4.1 Parking calls
If the call parking feature is enabled, users can park calls, so that they can be taken over by other users.
In order to park a call, press *6 during an active call. You will hear a message indicating the line number on which the call is parked in the system and the other party will be put on hold and hear music on hold.
The line number is needed if another user should pick up the call.
