1. A method, comprising:
- determining whether a user endpoint associated with an internet protocol multimedia subsystem session initiation message is registered;
when the user endpoint is determined to be unregistered, determining whether the internet protocol multimedia subsystem session initiation message is directed to a first exception endpoint listed in an exception endpoint list by performing a lookup in the endpoint exception list based upon a destination specified in the internet protocol multimedia subsystem session initiation message, the first exception endpoint corresponding to a service to establish an account for the user endpoint;
performing an electronic numbering query to obtain routing to the first exception endpoint; 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 first exception endpoint.

Abstract
Methods and apparatus for handling a communication session for an unregistered Internet Protocol Multimedia Subsystem (IMS) device are disclosed. An example method comprises receiving an IMS session initiation message from an un-registered user endpoint, determining whether the IMS session initiation message is directed to an exception endpoint, and establishing an IMS session on behalf of the unregistered user endpoint when the IMS session initiation is directed to the exception endpoint.

14. An apparatus, comprising:
-
a memory storing machine readable instructions; and a processor to execute the instructions to perform operations comprising; determining whether a user endpoint associated with an internet protocol multimedia subsystem session initiation message is registered; when the user endpoint is determined to be unregistered, determining whether the internet protocol multimedia subsystem session initiation message is directed to a first exception endpoint included in an exception endpoint list by performing a lookup in the endpoint exception list based upon a destination specified in the internet protocol multimedia subsystem session initiation message, the first exception endpoint corresponding to a service to register the user endpoint; performing an electronic numbering query to obtain routing to the first exception endpoint; 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 first exception endpoint. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A memory comprising instructions that, when executed, cause a machine to perform a method comprising:
determining whether a user endpoint associated with an internet protocol multimedia subsystem session initiation message is unregistered; when the user endpoint is unregistered, determining whether the internet protocol multimedia subsystem session initiation message is directed to a first exception endpoint identified in an exception endpoint list by performing a lookup in the endpoint exception list based upon a destination specified in the internet protocol multimedia subsystem session initiation message, the first exception endpoint corresponding to a service for registration of the user endpoint; performing an electronic numbering query to determine routing to the first exception endpoint; 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 first exception endpoint. - View Dependent Claims (25, 26, 27, 28)
