Abstract
Servers commonly require upgrades. Servers, such as communication managers (CMs), may enter into a “deny new service” state and continue to process existing calls. Networked components receive an OPTIONS message, and any new calls are processed through a different communication manager. Existing calls are “ReHomed” via a SIP PUBLISH message to a different communication manager.
