A testing system, also known as a call generator, generates telephone calls to test telephone equipment. The call generator includes a processor, a memory for storing processor procedures and test cases, and a communication interface. The procedures include a test case procedure for calling a system under test (SUT), interacting with the SUT, and accessing voice mailboxes located in the SUT. The call generator sends messages to the SUT. Then the call generator calls the SUT to once again access the voice mailboxes, and retrieves the stored messages. The call generator compares the retrieved messages with the delivered messages, or parameters representative of the delivered messages, to verify the retrieved messages. The call generator also has the capability to store, communicate, and verify other types of electronic information including facsimiles and electronic mail. The call generator may also operate on a network for communicating test cases and other database information to and from other users. The call generator and method are also applicable to testing private branch exchanges (PBX) and other telephone equipment.

Apparatus and method for generating calls and testing telephone equipment

A testing system for an interactive voice messaging system comprises a processor, a memory storing processor procedures and test cases, and a telephonic interface. The processor procedures include a master procedure and subprocedures for debugging the test case, retrieving and displaying documents, storing and retrieving database items, test case procedure development and editing, and test report generation. The processor procedures are all hyperlinked together so that the testing system can call any of the procedures at specified times in order to permit a user to read or modify database entries, documents and test cases when necessary. A method for testing an interactive voice messaging system includes steps for performing the test case control system of the present invention. The present apparatus and method are also applicable to testing private branch exchanges (PBX) and other telephonic based systems.
