2 The Voipfuture Difference: It s how we measure Voipfuture technology uses fixed time slicing to create atomic units of media quality. This means that each time slice of each stream of each call running through the network delivers data summaries relying on hundreds of metrics and indicators. These quality summaries each 5 seconds allow an adjustable depth of view. An aggregated KPI view to express precise performance of service and infrastructure A detailed view delivering root causes to pin point problem sources and impact level The aggregation to different levels does not only makes sense in a vertical respect. It provides data for very different use cases. For example, call quality data is essential for customer experience management, but less helpful for root cause analysis. Time slice and session data on the other hand give valuable insights into the overall network and service quality and provide a better high-level overview. Every time slice is a quality summary relying on hundreds of metrics and indicators. Every call, every stream delivers data each 5 second DEMO REPORT VOLTE & VOWIFI 2

3 Voipfuture s KPI system for next-generation voice services Whereas there are well defined KPIs to assess a network s SIP signaling performance there is no comparable means to determine media quality. Therefore Voipfuture introduces a new KPI system which offers different perspectives on the media quality of a VoIP service. GSR GCR It not only explains different quality perspectives but provides KPIs to translate information into action.

Which codecs are used by my service? How is the call setup success rate? Overall, and by direction What are the response codes? How often do codecs change in a call? How do changes affect quality? How is my radio access? Per cell Per enb 5
