Methods and apparatus for handling a communication session for an unregistered internet protocol multimedia subsystem (IMS) device

摘要

Methods and apparatus for handling a communication session for an unregistered Internet Protocol Multimedia Subsystem (IMS) device are disclosed. An example method includes, in response to receiving an internet protocol multimedia subsystem session initiation message from a user endpoint, determining whether the user endpoint is registered; and, when the user endpoint is determined to be unregistered: determining whether the internet protocol multimedia subsystem session initiation message is directed to an exception endpoint by performing a lookup on a list; determining whether a profile for the unregistered user endpoint is available; when the profile for the user endpoint determined to be unregistered is unavailable, loading a default profile; and establishing an internet protocol multimedia subsystem session on behalf of the user endpoint determined to be unregistered when the internet protocol multimedia subsystem session initiation message is directed to the exception endpoint.
