CUCM14 7960 running SIP and ExtensionMobility

In the latest release of Cisco Unified Communications Manager (CallManager) 14 the ExtensionMobility feature is no longer supported on Cisco 7960 IPphones running SIP firmware.

An administrator is unable to ‘ tick the box’ within the CM Administration Device \ Phone level to activate the Enable Extension Mobility option because it simply is not there anymore.

A workaround is to convert the Cisco 7960 IPphone from SIP to SCCP , this will allow you to activate and use EM and benefit from ALM PRO, the EM-SSO solution, again.
