Abstract
In certain embodiments, a system comprises a connection to a network and an application server providing a cross cluster extension mobility (CCEM) service configured to receive a request from a user to log into the CCEM service from a telephony device connected to the network, prompt the user via the telephony device to provide a user ID, determine whether the user is logging in from a home cluster or a remote cluster, and perform a local extension mobility login for the user.
