Purpose

Cisco Extension Mobility service, a feature of Cisco Unified CallManager, allows a device, usually a Cisco Unified IP Phone, to temporarily embody a new device profile, including lines, speed dials, and services.

The Cisco Extension Mobility service provides a fairly rich application programming interface (API), which enables extension mobility on IP phones and allows application control over authentication, scheduling, and availability.

An application that uses Cisco Extension Mobility service represents an IP phone service that allows a user to enter a userID and PIN at the phone itself and log into the phone. The architecture and implementation of extension mobility make many other applications possible.

Some examples follow:

An application that automatically activates phones for employees when they reserve a particular desk for a particular time (the scheduling application).

A lobby phone does not have a line appearance until a user logs in.

Audience

The Extension Mobility API Developers Guide for Cisco Unified CallManager 4.2(3) provides information for developers who write applications that extend the functionality of Cisco Extension Mobility service. Developers should be familiar with Extensible Markup Language (XML).

New and Changed Information

This section describes any new features and or changes in a release of Cisco Unified CallManager for Cisco Extension Mobility API developers.


Note No changes exist for Cisco Unified CallManager Release 4.2(3) except for the product name changes that you will see throughout this publication.


Cisco Unified CallManager Release 4.2(1)

The following list provides the features or changes for Cisco Extension Mobility service API developers in Cisco Unified CallManager Release 4.2(1):

Tomcat Servlet architecture replaces the ASP block.

Connection from the IIS to the Tomcat server uses the established Apache JServ Protocol (AJP) mechanism.

The Login Service Java Object runs in the Tomcat Servlet.

The Tomcat Servlet Logout Scheduler assumes the functionality that was previously performed by the Logout NT Service and contains a new data structure in the scheduling information.

Communication from the Cisco Extension Mobility service to the DBL uses JNI instead of COM.

Organization

The following organization applies for this guide.

Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool automatically provides recommended solutions. If your issue is not resolved using the recommended resources, your service request will be assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553 2447

For a complete list of Cisco TAC contacts, go to this URL:

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
