Telephone number monitoring

A system for monitoring phone numbers, comprising:

• a computing device including at least one processor and memory associated with the at least one processor;
• and
• a telephone network including a plurality of telephone numbers, wherein the computing device is configured to:
• obtain data directly from the telephone network, the data indicating call activity involving the phone numbers, respectively, during a time period having a preselected duration;
• automatically determine, 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;
• automatically place a test call to any of the phone numbers for which there were no successfully answered calls placed to the phone number during the time period;
• for each of the phone numbers to which a test call was placed, automatically determine whether the test call was successful;
• for any of the phone numbers to which the test call was not successful, automatically generate an indication of a problem with the phone number;
• determine, for each of the phone numbers, a baseline expectation of answered calls placed to the respective phone number based on the data associated with a prior time period;
• and
• generate an indication of a potential problem with the respective phone number when a quantity of answered calls placed to the phone number during the time period is less than the baseline expectation.
