Managing Microsoft Teams voice performance requires deep insight into all components of the call path involving coordination between IT departments and service providers, each working with different tools with different objectives. IT teams often struggle to qualify and solve application performance or voice quality issues because traditional monitoring tools don’t provide substantial insight into the user experience. IT teams are sometimes siloed, so collaborating on poor Microsoft Teams performance from a failing or misconfigured Session Border Controller (SBC) may result in an increased mean time to repair (MTTR).
And even if SBC devices are mostly reliable, problems with configuration, the network, certificates, security or sometimes just media overload can have dramatic consequences.

Finally, SBCs like AudioCodes also collect performance information for each call that enables the UC (unified communications) team to get a partial view of the route of the data from the Microsoft Teams cloud to the PSTN provider. But that stream of data often doesn’t go up to the user, which makes the overall troubleshooting complex.

On the other end, Microsoft Teams administrators see the performance of calls up to the SBC but can’t qualify the root cause of the issue if the SBC has issues or if the performance dropped on the way from the SBC to the PSTN provider.

Martello Vantage DX solves this issue by providing both UC and Microsoft Teams management teams with complete end-to-end visibility on calls and network performance by collecting, correlating and testing the entire route of the data from the user to the PSTN provider.

What is Martello Vantage DX for AudioCodes?

Martello Vantage DX™ provides IT teams with a single pane of glass that correlates data from AudioCodes, from the Microsoft Teams Call Quality Dashboard and from its own network path tests to rapidly resolve any call quality issue BEFORE it can impact end users.

Key AudioCodes Monitoring Features

Teams Call Icon

  • Provide end-to-end visibility on call quality by contextualizing the SBC call performance with the Microsoft Teams analytics.
  • Analyze each part of the user’s call path to determine where the latency is coming from.
  • Report on call flow & duration with detailed Jitter, RTT, Packet Loss and MOS score for all Microsoft Teams calls using AudioCodes.

Alert Icon
