Cisco CallManager provides two clusterwide service parameters for call park: Call Park Display Timer and Call Park Reversion Timer. Each service parameter includes a default and requires no special configuration.
Call Park Display TimerDefault specifies 10 seconds. This parameter determines how long a call park number displays on the phone that parked the call. Set this timer for each server in a cluster that has the Cisco CallManager service and call park configured.
Call Park Reversion TimerDefault specifies 60 seconds. This parameter determines the time that a call remains parked. Set this timer for each server in a cluster that has the Cisco CallManager service and call park configured. When this timer expires, the parked call returns to the device that parked the call.
