establish a persistent connection between a user agent (UA) and the SIP server; initiate an idle connection timeout countdown timer subsequent to establishing the persistent connection; initiate authentication of an initial REGISTER request using a first level of authentication subsequent to initiating the idle connection timeout countdown timer; terminate the persistent connection when the initial REGISTER request is not authenticated before expiry of the idle connection timeout countdown timer; and store a new binding for the UA in a registration repository when the initial REGISTER request is authenticated and remove the new binding when the persistent connection is dropped.
