/mcpPark Monitoring Periodic reversion timer: The frequency in which the user is reminded about the parked call. The range is 0-1200 seconds, with default value of 30 seconds. Park Monitoring Forward No Retrieve timer: This timer is started when the park monitoring reversion timer expires. This is how long, in seconds, the park reminder notification plays before the parkee is redirected to the parker's Park Monitoring Forward No Retrieve (FNR) destination. The range is 30-1200 seconds, with default value of 300 seconds. Park Monitoring Forward No Retrieve Destination is configurable on the line page in Cisco Unified Communications Manager Line page settings. Assisted DPark provides an alternative one step way to perform DPark operation on phones. When user performs Assisted DPark from newer phones and application is monitoring the parked party, Cisco Unified JTAPI provides reason CiscoFeatureReason.REASON_REFER in the connection events (ConnCreatedEv, ConnInProgressEv and CallCtlConnQueuedEv) for DPark DN. Currently when DPark is done, application gets connection events with CiscoFeatureReason.REASON_TRANSFER. Interface Changes See CiscoAddrParkStatusEv, on page 316 Message Sequences See Park Monitoring Support, on page 1206 Backward Compatibility Park Monitoring enhancements and Assisted DPark support are backward compatible. The new park reversion behavior improves the user experience to allow the parked call to be retrievable for as long as possible. It also improves the usability of the park feature by allowing the user to monitor the status of a parked call through the new event being delivered. Applications can conditionally enable/disable filter to receive event via setCiscoAddrParkStatusEvFilter() API on CiscoAddeEvFilter. By default this filter is disabled and therefore maintains backward compatibility. If the application uses a JTAPI client older than 7.1.2, the devices are not restricted but if the application tries to observe these devices (which supports this feature to be invoked manually), JTAPI throws an exception and marks these devices as restricted from there on. Park Reminder When a parked call is not retrieved for a specified time, a reminder call returns to the address that parked the call, and Park Number connection moves to the Disconnected state. The call reconnects and moves to the Established state. A terminal connection in Talking state gets created for the address that parked the call. Park Retrieval When a call is parked from an IP phone, the park number displays on the phone. Any terminal can unpark the call by dialing the park number. When a call is unparked, a new call gets created with connections to unparked address. The CallControlConnection for the park number in the original call, which is in the Queued state, moves to the Disconnected state.
