The purpose of this document is to describe the following Cisco Unified CallManager APIs:

The Cisco Unified CallManager AXL implementation allows applications to modify the Cisco Unified CallManager system database. AXL is not intended as a real-time API, but as a provisioning and configuration API.

Cisco Unified CallManager Real-Time information, Performance Counters, and Database information exposure occurs through the AXL Serviceability API.

The Cisco Unified CallManager Extension Mobility Service provides a rich API, which enables extension mobility on IP phones and allows application control over authentication, scheduling, and availability. It allows a device, usually a Cisco Unified IP Phone, to temporarily embody a new device profile, including lines, speed dials, and services. An application that uses the CiscoUnified CallManager Extension Mobility Service represents an IP phone service that allows a user to log in by entering a userID and PIN. The architecture and implementation of the CiscoUnified CallManager Extension Mobility Service make many other applications possible.

Some examples are:

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.

The Cisco Unified CallManager WebDialer application is installed on a Cisco Unified CallManager server. It enables click-to-dial functionality by creating hyperlinked telephone numbers in a company directory. This functionality allows users to make calls from a web page by clicking on the telephone number of the person they are trying to call.


The Cisco Unified CallManager Developers Guide provides information for developers who write applications that extend the functionality of the APIs described in this document.

This guide assumes the developer has knowledge of a high-level programming language such as C++, Java, or an equivalent language. You must also have knowledge or experience in the following areas:

Extensible Markup Language (XML)

Hypertext Markup Language (HTML)

Hypertext Transport Protocol (HTTP)

Simple Object Access Protocol (SOAP) 1.1

Socket programming

TCP/IP Protocol

Web Service Definition Language (WSDL) 1.1

In addition, users of the Cisco Unified CallManager APIs must have a firm grasp of XML Schema. For more information on XML Schema, refer to

The developer must also have an understanding of Cisco Unified CallManager and its applications. Documents on Cisco Unified CallManager and other related technologies are listed in the Related Documentation section.


The following organization applies for this guide.

Table 1 Organization 


Chapter 1 "AXL Programming"

This chapter describes the Administrative XML Layer (AXL) API, which provides a mechanism for inserting, retrieving, updating, and removing data from the database using an XML SOAP interface. This allows you to access Cisco Unified CallManager data using XML and receive the data in XML form.

Chapter 2 "AXL Serviceability API Programming"

This chapter describes the AXL Serviceability APIs, which are based on the SOAPISAPI.dll. Cisco Unified CallManager Real-Time information, Performance Counters, and Database information exposure occurs through the AXL Serviceability APIs.

Chapter 3 "Extension Mobility Service API Programming"

This chapter includes high-level concepts that are important in understanding the Cisco Unified CallManager Extension Mobility Service as well as an overview of configuring EM services, messages, message DTDs, and error codes.

Chapter 4 "WebDialer API Programming"

This chapter describes the Simple Object Access Protocol (SOAP) and HTML over HTTP (and HTTPS) interfaces that are used to develop customized directory search applications for Cisco Unified CallManager WebDialer.

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:

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

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.
