This article offers tips for preventing problems from occurring when deploying Internet protocol (IP) telephony service. The ultimate test of voice services lies with delivering delay-free, toll-grade service the first time and every time. In telephony vernacular, this requires five-9s performance--the ability to guarantee 99.999 percent performance in parameters such as network availability and voice quality. To achieve this goal, information technology managers considering mixing voice and data over their IP networks should apply a phased approach to equipment and network testing and service validation before going live. Once deployed, conducting ongoing performance monitoring becomes equally crucial, as long as the service mix and the network itself continue to grow and change. While services present a large and unique set of challenges, testing processes should confirm not only that voice and the IP network perform well together, but also that voice, data and other applications do not threaten each other's performance. IP network managers and designers should utilize a proper set of procedures and methods designed specifically to test the equipment, configurations and engineering designs that make up converged IP networks. With these tools, as well as a high level of cooperation between data and voice experts on staff, IP telephony validation testing can help companies avoid IP telephony failures.
