274 Chapter 27 Dialing plan: System settings
Calls are retrieved by pressing the intercom button and dialing the retrieval code. On model 7000
and analog telephones, pick up the receiver, and then dial <parkcode>25.
You also need to program the delay timer that determines when external parked calls that are not
answered return to the originating telephone. Refer to "Timers" in the Device Configuration
Guide (NN40020-300).
You can disable Call Park by setting the Park Code to None.
