Chapter 40 Cisco IP Phones
Phone Administration Tips
Directories Button
The Cisco IP Phone models 7970, 7960, and 7940 can display a directory of
employee names and phone numbers. Although you access this directory from the
directories button on the IP phone, you must configure it before users can access
it. To use the corporate directory, you must enter users into a Lightweight
Directory Access Protocol (LDAP) directory that is configured with
Cisco CallManager.
The URL Directories enterprise parameter defines the URL that points to the
global directory for display on Cisco IP Phone models 7970, 7960, and 7940
phones. The XML device configuration file for the phone stores this URL.
Tip If you are using IP addresses rather than DNS for name resolution, make sure that
the URL Directories enterprise parameter value uses the IP address of the server
for the hostname.
If the phone URL was not updated correctly after the URL Directories enterprise
parameter was changed, try stopping and restarting the Cisco TFTP service; then,
reset the phone.
Cisco CallManager User Options
Cisco IP Phone users can access the Cisco CallManager User Options through
their web browser, so they can configure a variety of features on their phone.
Some of the configurable features include call forward, speed dial, and personal
address book. By setting enterprise parameters as either True or False,
administrators can configure which features are made available to users; for
example, the administrator can set the Show Speed Dial Settings enterprise
parameter to False and users would not be able to configure speed dials on their
phones.
MaxPhonesFallBackQueueDepth Service Parameter
The Cisco CallManager service uses the MaxPhonesFallBackQueueDepth
service parameter to control the number of phones to queue on the higher priority
Cisco CallManager when that Cisco CallManager is available for registration.
