METHOD, DEVICE, AND SYSTEM FOR CONNECTING TO A COMMUNICATION DEVICE

摘要

A method and apparatus include a first server that communicates with a second server to cause a call back request to be communicated to an endpoint so that the endpoint can initiate a call back connection with the first server or a third server. Such a call back connection may occur near real time or in substantially real time so that updates can be supplied to an endpoint running an application supported by the server quickly and efficiently. The endpoint may register with the second server such that the second server is able to utilize notification messages for providing call back request information to the endpoint to advise the endpoint of a call back request.
