Abstract
The present invention provides a system, method and apparatus for authenticating an Internet Protocol (IP) phone and a user of the IP phone by determining whether the IP phone is an authorized device, and whenever the IP phone is authorized and a trigger condition occurs, determining whether the user of the IP phone is authorized. The user authorization process initiates a call to the IP phone, sends a request for a passcode to the IP phone, sends a message to disable the IP phone whenever the passcode is invalid, and terminates the call. The user authentication process uses an in-band channel and the IP phone does not run a two factor authentication client application during the authentication process.
