Guidelines and Tips
3. For XML services, the information in the phone configuration file points to a web script/file, which
returns an XML object. Because these services are not installed on the phone, the phone invokes the
service URL only when the user selects the option for the service on the phone.
The phone automatically uninstalls the Cisco-signed Java MIDlet under the following circumstances:
• When Cisco Extension Mobility is used to change the current active user on the phones, which
occurs during login and logout
• If a phone user is not logged into the phone via Cisco Extension Mobility, but the Owner User ID
field is updated in Cisco Unified Communications Manager Administration (which changes the
current active user for the device)
• If the phone registers with a different Cisco Unified Communications Manager cluster that does not
support Cisco-signed Java MIDlets (or if the other cluster has a different service configuration for
the device)
• If the configuration is cleared on the phone by any method; for example, via the Settings menu on
the phone or a factory reset on the phone.
Tip Cisco Unified IP Phone models support IP phone services provisioning differently; for example, the
Cisco Unified IP Phone 7941G, 7941G-GE, 7961G, 7961G-GE, 7942G, 7962G, 7945G, 7965G, 7970G,
7971G, and 7975G can parse the service information from the phone configuration file, can support
movement of services to the Message, Directory, and Services buttons/options on the phone, and so on;
for example, the Cisco Unified IP Phones 7906G, 7911G, and 7931G do not support Cisco-signed Java
MidLets, but these phones can parse the service information from the phone configuration file. To
determine the service provisioning support for your phone model, refer to the Cisco Unified IP Phone
Administration Guide that supports your phone model and this release of Cisco Unified Communications
Manager.
Guidelines and Tips
Consider the following guidelines and tips when you provision IP phone services in Cisco Unified
Communications Manager Administration:
To minimize the impact to Cisco Unified Communications Manager performance and call processing,
do not put IP phone services on any Cisco Unified Communications Manager server at your site or any
server that is associated with Cisco Unified Communications Manager, such as the TFTP server or
publisher database server.
If you do not want to display the service on the phone, uncheck the Enable check box in the IP Phone
Services Configuration window (Device > Device Settings > Phone Services).
If you want to display IP phone services on a different button than the button that is specified as the
default, update the Services Type setting.
If you change the default service URL for a Cisco-provided default service, for example, you change the
service URL for the corporate directory from Application:Cisco/CorporateDirectory to a custom URL,
make sure that you choose Both from the Service Provisioning drop-down list box. (See
“Cisco Unified
IP Phone Service Configuration Checklist” section on page 35-1 .)
If you want to do so, you can configure the Services Provisioning enterprise parameter, which applies
the configuration to all phones in the cluster that support IP phone services. (In Cisco Unified
Communications Manager Administration, choose System > Enterprise Parameter.)
