Voice over IP (VoIP)

VoIP networks depend on many hardware and software components, and each component is in itself a complex hardware/ software system. As the system complexity increases, implementation mistakes become ever more likely. These flaws create opportunities for service interruptions in VoIP systems, which can degrade this very latency-sensitive service, leading to voice quality issues or even downtime.

Case Study

One major U.S.-based service provider understands firsthand that the ability to test product robustness, availability and security has a direct, measurable impact on the bottom line. VoIP deployments are rapidly growing.  In fact, by 2012, IBISworld forecasts revenue growth of 90.2 percent, bringing total revenue to $4.88 billion. By the same time, they predict that the U.S. will have approximately 25.4 million paying VoIP subscribers.  According to InStat, worldwide cable telephony service revenues are on track to reach $12.6 billion in 2008, up from $10.7 billion in 2007. Total worldwide cable telephony subscribers are projected to reach 37 million by the end of 2008, and rise to over 64 million by 2012.

This provider knows that its ability to maintain its edge in these highly competitive businesses hinges on the ability to rapidly develop and deploy innovative revenue-generating services, including hosted VoIP, real-time conferencing, streaming media and other interactive services. But as it pleases customers with hot new services, it must still meet or exceed industry-standard targets for stability, reliability and availability: 99.999% uptime.

• Rapidly roll out innovative, revenue-generating VoIP services while ensuring that those services meet the expected service availability and reliability levels
• Prevent costly service outages and degradation, and reduce customer churn and subscriber support costs
• Identify potential sources of service quality issues before they impact the customer experience or VoIP infrastructure performance
• Integrate multiple implementations of the Session Initiation Protocol (SIP) from a wide spectrum of vendors while delivering a stable service to subscribers

• Improved service availability for VoIP and unified-communication services, establishing processes to maximize uptime of additional services such as video streaming
• Reduced customer churn and improved bottom line as a result of significantly improved VoIP service quality
• Identified a zero-day vulnerability in a session border controller, which was patched prior to service rollout
• Automated and conducted comprehensive testing of vendor products more efficiently, and streamlined problem resolution process with vendors
