A comprehensive suite of network testing solutions, from VoIP and Bandwidth Quality testing to worldwide edge-to-edge deployments. VoIP & Video Quality testing is essential to maintaining the user experience across VoIP applications, such as voice calls and video conferencing. Conventional "speed" tests are meaningless without understanding the testing protocol. Bandwidth quality is the key to solving user experience issues. Automated testing provides a seamless and secure way to gather key network performance data across single and multi-edge networks. Regardless of the application, the user experience is everything. Configure in-depth tests to ensure a network is fit for purpose. Determine if the capacity of a connection is adequate for the load being expected of it. Even large capacity connections can be over-subscribed.
