A comprehensive suite of solutions for network testing, from VoIP and Bandwidth Quality Testing to worldwide edge-toedge deployments. VoIP & Video quality testing is crucial to maintain the user experience for VoIP applications such as voice calls or video conferencing. Conventional "speed tests" are meaningless if you don't understand the testing protocol. The key to solving issues with user experience is bandwidth quality. Automated testing is a secure and seamless way to collect key network performance data for single- and multi-edge networks. The user experience is critical, regardless of the application. Configure detailed tests to determine if a network is suitable for its intended purpose. Determine if a connection's capacity is sufficient for the load that it will be expected to handle. Even connections with large capacities can be oversubscribed.
