Registration status management for endpoint devices

摘要

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.

主权项

1. A method comprising:
transmitting, by a computing device to a user device, a request for a registration state value; receiving the registration state value in response to the request; determining a registration state error value based on a correspondence between the registration state value and the registration state error value of a plurality of registration state error values, wherein each of the plurality of registration state error values is associated with one of a plurality of different values indicating an out-of-service no dial tone condition; determining a registration state error category associated with the registration state error value, wherein the registration state error category is one of a plurality of registration state error categories each corresponding to one or more possible causes for the out-of-service no dial tone condition and one or more respectively associated possible solutions; determining a possible cause for the out-of-service no dial tone condition from the one or more possible causes for the out-of service no dial tone condition associated with the registration state error category; and determining a possible solution associated with the possible cause for the out-of-service no dial tone condition.
