Phone Failover and Fallback

Phone Failover and Fallback

This section describes how phones fail over and fail back if the

Cisco CallManager to which they are registered becomes unreachable. This section also covers conditions that can affect calls that are associated with a phone, such as reset or restart.

Cisco CallManager Fails or Becomes Unreachable

The active Cisco CallManager designation applies to the Cisco CallManager from which the phone receives call-processing services. The active Cisco CallManager usually serves as the primary Cisco CallManager for that phone (unless the primary is not available).

If the active Cisco CallManager fails or becomes unreachable, the phone attempts to register with the next available Cisco CallManager in the Cisco CallManager Group that is specified for the device pool to which the phone belongs.

The phone device reregisters with the primary Cisco CallManager as soon as it becomes available after a failure. See the “MaxPhonesFallBackQueueDepth Service Parameter” section on page 40-45for information about phone registration during failover.

Note Phones do not failover or fallback while a call is in progress.

Phone is Reset

If a call is in progress, the phone does not reset until the call finishes.
