Abstract
Methods, logic, apparatus, and systems are provided to support cross cluster directory number (DN) extension mobility (EM) using dynamic network distributed dial-peer updates in a communication networks, which includes a plurality of clusters or systems and each of the plurality of clusters including a call control agent (CCA). Identification data corresponding to an identity of an associated user is received into a first cluster of a multiple cluster telecommunication network. A directory number and associated first telecommunication device corresponding to the user are registered with a first call control agent of the first cluster in accordance with received identification data. Registration data corresponding to the registered directory number is communicated to at least a second cluster of the telecommunications network. An incoming connection request associated with the registered directory number is routed directly to the first CCA without redirection to any other CCAs within the multiple cluster telecommunication network.
