A device and method for testing a telephone circuit in which a caller takes advantage of available caller identification information to complete a ringback test, device is accessed by a caller who may not be aware of the telephone number from which he is calling when the caller completes a call to a telephone number assigned to the device. As the caller is accessing the test device, the test device detects the caller identification available between the first and second rings to identify the caller's telephone number, and answers the call after the second ring. The test device presents the telephone number to the caller. The caller ID information may be display-formatted at the test device and provide a visual display.
