More than one third of network engineers working for VoIP providers detect problems in the client-facing network by receiving complaints from subscribers. The damning finding for telecoms experts is revealed in new research that says only 20 per cent of VoIP providers use monitoring systems to ensure quality service. According to Web and VoIP specialist, Empirix, the most dominant response however from 150 VoIP firms was that subscriber complaints proved the main source for identifying problems. Media problems are the most irksome for network engineers, such as the audio quality of call, followed by the second but rapidly declining threat to VoIP of signalling glitches. Most engineers perceive signalling problems, which include reliability and efficiency as lessening in severity; while in contrast, anxiety over the quality of calls will dominate client concerns until 2008. Phil Odence, Empirix VP, said the increasing fixation with the quality of media transmissions came as “no surprise.” “Any service provider offering VoIP is experiencing dramatic growth in their subscriber base which eventually stresses network bandwidth constraints,” he said. Recent surveys show voice quality and clarity are the biggest concerns for companies deploying VoIP services, Empirix said. Some have even taken steps to ensure media quality further emphasises the need for more efficient ways to detect problems than subscriber complaints. “Waiting for subscribers to complain about service quality is clearly not a sustainable operations model for VoIP service providers,” said Jessy Cavazos, researcher at Frost & Sullivan. “To be successful, as service providers transition from service introduction to ramp to full deployment, they need to proactively monitor live traffic to gain insight into service quality and network behaviour. We believe this will be a major growth area for the industry in 2006.” According to the study, when asked how their network engineers most often initially find out about problems in the VoIP network, the dominant response (36 percent) was, “subscriber complaints.” Only a fifth of those companies polled report using VoIP application monitoring systems to ensure service quality The company claims that unlike most VoIP monitoring solutions that focus on signaling quality, its Hammer XS product measures both media and signaling quality for live VoIP traffic.
