Cisco CallManager Extension Mobility Overview
The Cisco CallManager Extension Mobility feature allows users within a
Cisco CallManager cluster to configure any Cisco IP Phone7960/7940 as their
own, temporarily, by logging in to that phone. Once logged in , the phone adopts
the user’s personal phone number(s), speed dials, services links and other
user-specific properties. After logout, the phone adopts the or iginal user profile.
With Cisco CallManager ExtensionMobility, several employees can share office
space on a rotational basis instead of having a designated office.This approach is
commonly used in work environments such as sales offices and consulting firms
where employees do not routinely conduct business in the same place or keep the
same hours every day.

Login Service

Administrators can program the login service, an XML-based authentication
service, for a variety of uses, including duration limits on p hone configuration and
login authorization for particular phones. Program ming is done in
Cisco CallManager Service Parameters Configuration.
The user interface to the login service is accessed through the Services button on
Cisco IP Phone Models 7960 or 7940. The user en ters login information in the
form of a UserID and a Personal Identification Number (PIN). The
Login Application receives the XML-over-HTTP request and verifies the
information against the Cisco IP Telephony Directory (see Figure 1-1). The
phone is reconfigured automatically with the individual user device profile
information.
