<p>The present invention automatically initiates a telephone call to a given destination (4). At the same time, the progress of the call is monitored. The time of a ring back and voice answer received from the destination (4) are recorded to an output file. At the end of the voice answer, a pre-recorded voice message is sent by the system (2) to the person answering at the destination (4). Thereafter, the recorded data is used to determine the response time for that particular telephone destination. A plurality of destinations can be tested. A second embodiment of the present invention provides for the interactive correspondence between a remote evaluation unit and a called destination and the measurement of the performance characteristics of the telephone network.</p> |
