Abstract
Methods, systems, and computer readable media for providing legacy devices access to a session initiation protocol (SIP) based network are disclosed. One exemplary system comprises a session initiation protocol (SIP) based access proxy element communicatively coupled to a SIP based network that includes a registration engine configured to create a mapped entry in a database that associates an assigned SIP registration identifier to an identifier corresponding to a legacy endpoint device and configured to register the legacy endpoint device into the SIP based network using the assigned SIP registration identifier. The SIP based access proxy element further includes a session management module configured to establish a communications session involving the registered legacy endpoint device by interworking between a legacy control protocol and a SIP based call control protocol using the mapped entry in the database.
