1. A method, comprising:
- receiving, at a Session Initiation Protocol (SIP) enabled communication endpoint, controller information related to a first controller;
receiving, at the communication endpoint, controller information related to a second controller;
analyzing the controller information related to both the first and second controllers; and
based on the analyzing step, the communication endpoint selecting at least one of the first and second controllers as its controller.

Abstract
Provided are methods, devices, and systems for maintaining a SIP survivable network. The present invention is adapted to allow SIP endpoints or User Agents to discover and select the controller or controllers that the SIP endpoint will register with. Selection of the controller or controllers may be based upon the relative attributes of the controllers and the needs of the SIP endpoint.
