Cisco Extension Mobility The Cisco Extension Mobility (Extension Mobility) service, a feature of Unified Communications Manager, allows a device, usually a Cisco Unified IP Phone, to temporarily embody a new device profile, including lines, speed dials, and services. It enables users to temporarily access their individual Cisco Unified IP Phone configuration, such as their line appearances, services, and speed dials, from other Cisco Unified IP Phones. The Extension Mobility service works by downloading a new configuration file to the phone. Unified Communications Manager dynamically generates this new configuration file based on information about the user who is logging in. You can use the XML-based Extension Mobility service API with your applications, so they can take advantage of Extension Mobility service functionality. For more information, See the Extension Mobility API Tech Center on the Cisco Developer Network http://developer.cisco.com/web/emapi/home.

Device Monitoring and Call Control Interfaces The following are the device monitoring and call control interfaces of Unified Communications Manager: Cisco TAPI and Media Driver Unified Communications Manager exposes sophisticated call control of IP telephony devices and soft-clients using the Computer Telephony TAPI interface. Cisco's Telephone Service Provider (TSP) and Media Driver interface enables custom applications to monitor telephony-enabled devices and call events, establish first-and third-party call control, and interact with the media layer to terminate media, play announcements, record calls.
