Abstract
Systems and methods are for registering and authenticating an unmanaged IP device to an IP multimedia subsystem (IMS). An exemplary method includes implementing a system from which an unmanaged IP device retrieves IMS credentials needed to register and authenticate to the IMS. The system is remote to the unmanaged IP device and is accessible to the unmanaged IP device through an IP access network. The method further includes permitting the unmanaged IP device to register and authenticate to the IMS with the IMS credentials received from the system.
