Typical IP phone services that might be supplied to a phone include weather information, stock quotes, and news. Deployment of Cisco Unified IP Phone services occurs using the HTTP protocol from standard web servers, such as the Apache web services.
A user can access a service from the supported phone model in two ways. The user can press the Services button, or the user can use a preconfigured phone button. When the user presses the Services button, the phone uses its HTTP client to load a specific URL that contains a service or menu of services to which the phone is subscribed. The user then chooses a service from the listing by clicking the Select softkey.
Users can subscribe only to services that are configured through CUCM Administration. The following information is configured for each service:
■ URL of the server that provides the content
■ Service name and description, which help end users browsing the system
■ A list of parameters that are appended to the URL when it is sent to the server
These parameters personalize a service for an individual user. Examples of parameters include stock ticker symbols, city names, Zip codes, and user IDs.
From CUCM Administration, a lobby phone or other shared devices can be subscribed to a service.
After the system administrator configures the services, users can log in to the Cisco Unified IP Phone User Options and subscribe to services. From the Cisco Unified IP Phone User Options, users can subscribe to any service on their phone. (Subscriptions occur on a perdevice basis.)
Guidelines and Tips
A Cisco Unified IP Phone displays graphics or text menus, depending on how the services are configured.
The Cisco Unified IP Phone 7960 supports the HTTP header that is sent with any window that includes a Refresh setting. After a fixed time, a new window can replace any XML object that displays. The user can force a reload by quickly pressing the Update softkey. If a timer parameter of 0 was sent in the header, the window moves only to the next window when you press the Update softkey. The window never automatically reloads.
The Cisco Unified IP Phone 7960 supports the following softkeys that are intended to help the data-entry process:
■ Submit: This softkey indicates that the form is complete and that the resulting URL should be sent via HTTP.
■ <<: Use the Backspace softkey to backspace within a field.
■ Cancel: This softkey cancels the current input.
Use the vertical scroll button for field-to-field navigation.
NOTE Do not put Cisco Unified IP Phone services on any Cisco Unified CUCM server at the local site or any server that is associated with CUCM, such as the TFTP server or directory database publisher server. This precaution eliminates the possibility that errors in a Cisco Unified IP Phone service application will impact CUCM performance or interrupt call-processing services.
To configure IP phone services links in CUCM Administration, navigate to Device > Device Settings > Phone Services. Click the Add New button. The IP Phone Services Configuration window will display.
Enter the service name, description, and URL settings for the service and click Save. To apply changes to an existing service, update the IP Phone Services Configuration window by clicking Update Subscriptions to rebuild all user subscriptions. Subscriptions must be updated if the service URL was changed, a phone service parameter was removed, or a parameter name for a phone service was changed.
