Sonus Simplifies Microsoft Lync QoE Management for SBC 1000 and 2000 Customers

January 15, 2014

SIP communications company Sonus Networks (News - Alert) has released new software enhancements for its SBC 1000 and SBC 2000 session border controllers, which are meant to help customers increase quality of experience (QoE) in Microsoft Lync Enterprise Voice environments. In particular, Sonus is helping enterprises to optimize their Lync Enterprise Voice deployments by securing SIP trunking services at the border network, while providing a more seamless flow of SIP-based multivendor media for unified communications.


Microsoft’s (News - Alert) QoE technology already allows network operators to monitor and troubleshoot media quality for Lync calls by leveraging diagnostics and statistics collected by the Lync Monitoring Server. However, SBCs typically don’t report statistics for the entire call path to the Lync Monitoring Server, preventing network operators from getting the complete call flow picture.

With release 3.1 of the SBC 1000 and SBC 2000, Sonus is the first company to support native media quality monitoring for the entire Lync call, including the SIP trunk. Indeed, these products now gather information regarding delay, jitter and packet loss, allowing network engineers to better monitor and troubleshoot call QoE issues for an entire session.

This allows customers to do away with third-party monitoring tools for a much simpler and more cost-efficient way to monitor QoE when managing Microsoft Lync voice environments. According to Matt Landis, industry consultant and CEO of Landis Computer, this type of functionality should be present in all SBCs, IP phones, gateways and endpoints designed for Lync and obviously Sonus agrees.

Indeed, according to Sonus, the rapid adoption of Lync and other advanced UC technologies has made the management of communications networks much more complex. Fortunately, the inclusion of the SBC 1000 and SBC 2000 under the Sonus Element Management System helps provide customers with a way to minimize this complexity. Along with the Sonus SBC 5000 and SBC SWe SBC series, these products allow Sonus customers to centrally manage the impact of communications on overall business performance from the branch office to the data center.
