Abstract: The present invention provides a system and method for testing and certifying one or more aspects of a device, such as a network, telecommunications, or computing device. One or more pre-defined or user-specified tests are identified by a user and applied by a testing entity to an aspect of the device. The results of the test are gathered and compared to one or more pre-determined standards. If the product passes the test, the device is certified by the testing entity and the results are published in an online catalog accessible via the Internet. Additionally, the product vendor is granted a license to use a certification logo in connection with the product. If the product fails the test, a private communication is sent from the testing entity to the product vendor indicating the failure. Any desired test can be applied to one or more aspects of a product, such as Voice-over-IP (VoIP) capabilities and other desired features of the product.
