Abstract:
A registration status manager may poll a user device, such as a session initiation protocol (SIP) endpoint device, for a registration state value indicative of its registration state. The registration status manager may receive the registration state value and determine that it indicates a registration state error such as an out-of-service no dial tone (NDT) condition. The registration status manager may determine a possible cause for failure associated with the registration state error. Subsequently, the registration status manager may determine a possible solution associated with the possible cause for failure.
