TELECOMMUNICATION SYSTEM TESTER WITH INTERGRATED VOICE AND DATA

An apparatus and method for testing a telecommunication system, which runs telephony applications such as voice-mail, telephone banking systems, automated directory assistance, and multi-branched telephone customer service systems. The apparatus includes a test computer for scheduling and controlling the execution of test scripts, which include commands for generating network signaling, voice data, and digital data used to simulate transactions that typically take place on the telecommunication system; a database for storing the test scripts, test script input data, and test results; channels for running multiple test scripts in parallel; and, serial and voice ports for transmitting and receiving voice data and digital data to and from the telecommunication system.
