Chapter 35 Cisco Unified IP Phone Services
Installation/Upgrade Considerations for IP Phone Services
If the service is marked as an enterprise subscription, the service displays on all phone in the cluster,
unless you disable the service in Cisco Unified Communications Manager Administration (by
unchecking the Enable check box in the Phone Services Configuration window).
When the user clicks the Subscribe button, Cisco Unified Communications Manager builds a custom
URL and stores it in the database for this subscription. The service then appears on the device
services list.
• Configure a list of parameters for the phone service. These parameters personalize a service for an
individual user. Examples of parameters include stock ticker symbols, city names, zip codes, or user
IDs. To determine the parameters for your IP phone service, refer to the documentation that supports
your IP phone service.
Tip Phone service provisioning allows you to install Cisco-signed Java MIDlets or XML applications on the
phone. In addition, IP phone service provisioning provides Cisco-provided default services after an
installation or upgrade.
Installation/Upgrade Considerations for IP Phone Services
If you provisioned services before a Cisco Unified Communications Manager upgrade, you may need to
perform additional configuration tasks after the upgrade. For example, if you use a custom directory that
points to a specific service URL, you may need to update the Service Provisioning drop-down list box.
If you upgrade Cisco Unified Communications Manager and your services do not display or work on the
phone, change the Service Provisioning setting to Both.
Cisco Unified Communications Manager automatically provisions Cisco-provided default services,
which are described in
“Finding an IP Phone Service” in the Cisco Unified Communications Manager
Administration Guide. These services display in the Find and List IP Phone Services window (Device >
Device Settings > Phone Services). To update these services, click the link in the window. You can
change the name of the service, where the default service displays on the phone, and the service URL.
If you change the service URL for the default services, choose Both from the Service Provisioning
drop-down list box, which allows you to support various phone models in your network; that is, your
network can support phone models that can retrieve the service information from the phone
configuration file and phone models that can retrieve the service information from an external service
URL (for example, the Cisco Unified IP Phone 7960).
Phone Support for IP Phone Services
Consider the following process, which indicates how a Cisco Unified IP Phone supports XML services
and Cisco-signed Java MIDlets:
1. The phone receives its configuration file after a reset, restart, or boot up and updates its local service
configuration if changes exist.
2. If any service in the configuration file is a Cisco-signed Java MIDlet, the phone compares the
provisioned Java MIDlet services to the list of installed Java MIDlet services to determine whether
the services need to be installed, uninstalled, upgraded or downgraded. The phone automatically
attempts to perform the necessary actions. If the phone fails to install the Java MIDlet on the phone,
the phone retries to perform the necessary actions.
