Directed Call Park Restrictions Restriction Feature Unified Communications Manager one party can park only one call at each Directed Call Park number. You cannot delete a Directed Call Park number that a device is configured to monitor (using the BLF button). A message indicates that the Directed Call Park number or range cannot be deleted because it is in use. To determine which devices are using the number, click the Dependency Records link on the Directed Call Park Configuration window. Directed Call Park number A caller who has been parked (the parkee) by using the Directed Call Park feature cannot, while parked, use the standard call park feature. Standard Call Park Feature We recommend that you do not press both the Transfer and Directed Call Park buttons simultaneously, as this may result in both DPark and Transfer failures. Directed Call Park Feature The Directed Call Park BLF cannot monitor a range of Directed Call Park numbers. A user can monitor only individual Directed Call Park numbers by using the Directed Call Park BLF. For example, if you configure a Directed Call Park number range 8X, you cannot use the Directed Call Park BLF to monitor that whole range of 80 to 89. Directed Call Park BLF The following limitations apply to Directed Call Park for phones that are running SIP: • Directed Call Park gets invoked by using the Transfer softkey on Cisco Unified IP Phones 7940 and 7960 that are running SIP. • The system does not support directed call park when the Blind Transfer softkey is used on Cisco Unified IP Phones 7940 and 7960 that are running SIP. • The system does not support directed call park BLF on Cisco Unified IP Phones 7940 and 7960 that are running SIP, and third-party phones that are running SIP. Directed Call Park for phones that are running SIP Troubleshooting Directed Call Park User Cannot Retrieve Parked Calls User cannot retrieve parked calls. After dialing the directed call park number to retrieve a parked call, the user receives a busy tone, and the IP phone displays the message, “Park Slot Unavailable”. Ensure that the user dials the retrieval prefix followed by the directed call park number.
