PARK button that is lit is pressed while talking, the system interprets that
a user wants to park a current call rather than to retrieve the parked call.
When the PARK button is pressed in the Consultation Hold state, the call
is parked on Consultation Hold, regardless of the LED state. To retrieve a
parked call in the Consultation Hold state, a user enters the Park
retrieving access code. When the parked call is activated and the Hold
indication for another appearance of the GCO button is Enabled, the user
can retrieve a parked call by pressing this button.
When a call is parked, a park timer is actuated regardless of the orbit
type. When the timer expires, the station that handles the parking is
recalled. The recalling method follows Recall Treatment.
When an extension station retrieves a parked call in remote nodes, the
speech path is connected by join connection in remote nodes. After the
two-way call is established, the IPedge path replacement is performed
between the Parked party and the Park retrieving party by the Network
CT Rerouting procedure (defined in an ECMA standard). The following
examples are for a 2 nodes case and a 3 nodes case.
