Patent ID: 8644823

Claim:
A method for use on a SIP (Session Initiation Protocol) server for updating bindings, comprising: receiving a SIP message concerning a particular Address-of-Record (AOR); and updating a list of one or more bindings for the particular AOR in a shared registration repository, wherein the shared registration repository is accessible by number of SIP servers and includes bindings for multiple AORs, wherein the updating comprises: updating a value of an idle timeout parameter in the shared registration repository, wherein the idle timeout parameter defines an idle timeout interval which specifies a time interval in which the list of one or more bindings stored in the shared registration repository for the particular AOR is permitted to remain inactive; and removing a binding associated with the SIP message from the list of one or more bindings in the shared registration repository for the particular AOR when the idle timeout interval associated with the list of one or more bindings has expired.
