Automated Analytics and Multi-level Diagnostics for VoIP and VoLTE Voice Services

NETSCOUT's Omnis Voice applies automation and AI/ML technology to reduce the complexity associated with the problem isolation of next generation voice services for VoIP and VoLTE. Interoperability challenges centered around handovers, device proliferation, associated software versioning, and coverage increase the amount of information that service providers track when evaluating and assuring their subscribers’ experience with SIP and RTP-based voice service.

A new approach is necessary to effectively manage the daily deluge of data, KPIs and improve focus on and dedication of resources to the performance issues with real business impact.

With Omnis Voice, automation is applied to voice services with modern AI/ML techniques to identify users and populations of users experiencing issues such as registration, setup latency. call attempts, call drops, MOS, and audio gaps, just to name a few.  Correlated information about specific populations experiencing variances in performance are categorized as outliers and subjected to next-level computer-based diagnostics.

Resulting information supports guided investigation of the performance issues experienced alongside evaluations of potential contributing sources (RAN, Core, IMS, Handset Type, Software version, etc.). Armed with evidence and localization of problems, service providers can prioritize troubleshooting resources where resolution has the most business impact.

Omnis Voice Understands the Business Impact of Audio Gaps

In addition to network components, other factors such as handset or even the time of day can contribute to a poor voice experience. Omnis Voice is uniquely equipped to account for non-network factors with an embedded ability to consider and evaluate both handset models and software versions in use.

Leveraging the voice service expertise that is evident in ISNGs ability to collect and calculate complex metrics around audio gaps (beginning gap, middle gap, short gaps, gap duration), NETSCOUT’s Omnis identifies the users impacted by audio gaps and then groups them by software version.

Once grouped, Omnis Voice machine learning techniques are applied to tag the impacted users running software versions with performance that deviates from those around them (outlier identification).

Performance outliers undergo next-level, deeper analytics using available data sets (Core and RAN when available) from nGenius Business Analytics to deliver evidence and smart outcomes that localize specific network infrastructure and calling scenarios contributing to reported business impacts.
