Phantom Park Issues

There is a rare condition wherein calls will remain visible in the Parking lot after they have been either retrieved or hung up. The counter will count down to zero, the call with briefly disappear, the call will reappear and the process starts over again.

It appears that it can affect all versions of CallManager prior to version 10.x.
In essence, after the call is no longer in the Parking slot, we are not getting an UnPark Event from CallManager

There is a fix available by contacting Cisco TAC. Reference the following numbers.

CSCty67720 - CTI handler leak in Callpark manager
CSCty04584 - Idle event not reported in hunt list RNA race scenario
