Chapter 40 Cisco IP Phones

Phone Administration Tips

The default specifies 10 phones per second. If a primary Cisco CallManager were to fail, the phones will fail over to the secondary Cisco CallManager. The failover process happens as fast as possible, using the priority queues to regulate the number of devices that are currently registering.

When the primary Cisco CallManager recovers, the phones get returned to that Cisco CallManager; however, you do not need to remove a phone from a working Cisco CallManager, in this case the secondary, as fast as possible because the phone is on a working system. The queue depth gets monitored (using the MaxPhonesFallBackQueueDepth service parameter setting) to determine whether the phone that is requesting registration gets registered now or later. If the queue depth is greater than 10 (default), the phone stays where it is and tries later to register to the primary Cisco CallManager.

In the Service Parameters Configuration window, you can modify the MaxPhonesFallBackQueueDepth service parameter. If the performance value is set too high (the maximum is 500), phone registrations could slow the

Cisco CallManager real-time response. If the value is set too low (the minimum is 1), the total time for a large group of phones to return to the primary

Cisco CallManager will be long.

Dependency Records

If you need to find out what directory numbers a specific phone is using or what phones a directory number is assigned to, click the Dependency Records link that is provided on the Cisco CallManager Administration Phone Configuration or Directory Number Configuration window. The Dependency Records Summary window displays information about directory numbers that are using the phone. To find out more information about the directory number, click the directory number and the Dependency Records Details window displays. If the dependency records are not enabled for the system, the dependency records summary window displays a message.

For more information about Dependency Records, refer to “Accessing Dependency Records” and “Removing a Directory Number from a Phone” in the Cisco CallManager Administration Guide.
