Abstract
A system for monitoring phone numbers includes a computing device having at least one processor and memory associated with the processor. A telephone network supports a plurality of telephone numbers. The computing device is configured to obtain data directly from the telephone network. The data indicates call activity involving the phone numbers, respectively, during a time period having a preselected duration. The computing device determines, for each of the phone numbers, whether the data indicates that there were no successfully answered calls placed to the phone number during the time period. For any such phone number, the computing device places a test call to the phone number. In the event that the test call is not successful, the computing device provides an indication of a problem with the phone number.
