ABSTRACT:
Reliability of telephone service is increased by providing a test call apparatus configured to launch a test call to a preselected telephone number in response to a call from a remote location requesting that the test call be placed. The test call apparatus launches the test call as if the call were being made from the user-supplied originating area code, exchange, or phone number. The test call apparatus then bridges the requesting call and the test call to facilitate analysis of the routing of the test call.
