Report
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.
The Voipfuture Difference: It‘s how we measure
2DEMO | REPORT VOLTE & VOWIF I2017
Every time slice is a quality summary relying on hundreds of metrics and indicators. Every call, every stream delivers data – each 5 second.

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.
It not only explains different quality perspectives but provides KPIs to translate information into action.
