Abstract
A method to support cross cluster extension mobility (CCEM) in a communication network, which includes a plurality of clusters, each of the plurality of clusters including a call manager, the method includes receiving a request for cross cluster extension mobility from a user on a first telephony device located in a first cluster; adding a second telephony device in a home cluster for the user, only if the first cluster is different from the home cluster. The method further includes performing extension mobility login for the user on the first telephony device; and configuring a Trivial File Transfer Protocol (TFTP) service parameter of the call manager in the first cluster.
