RadiSys adds VQE to Convedia media server

RadiSys announced today it has added voice quality enhancement (VQE) features to its Convedia Media Server. The new VQE solution removes common sources of poor voice quality in VoIP conferencing applications, including noise, packet loss and echo, and captures statistics for voice quality measurement suitable for upholding SLAs.

RadiSys VQE implements noise gating, noise reduction and noisy line detection mechanisms. The new VQE technology also includes packet loss concealment by intelligently restoring audio packets lost or unacceptably delayed by traffic congestion on the Internet. Convedia media servers with VQE also remove acoustic echo by continuously monitoring all VoIP call legs, dynamically detecting echoes and selectively applying echo cancellation.

All VQE features are supported with new audio and packet statistics, allowing conferencing service providers to continuously measure audio quality for performance measurement and support SLAs with customers.

Benefits of the VQE package embedded into Convedia media servers include improved audio quality, minimized end-to-end delay, streamline network integration, and reduced capital expenditures and ongoing operational costs through consolidated utilization of network equipment resources (i.e. fewer network boxes means lower total cost of ownership).
