Innovative Design Resolves Key VoIP Quality Challenges for Conferencing Service Providers
HILLSBORO, Ore. -- RadiSys[R] Corporation (NASDAQ:RSYS), a leading global provider of advanced embedded solutions, today announced the addition of Voice Quality Enhancement (VQE) features for the RadiSys Convedia[R] Media Server. The new VQE solution removes the common sources of poor voice quality in VoIP conferencing applications, including noise, packet loss and echo, in addition to capturing statistics for voice quality measurement suitable for upholding service level agreements (SLAs). Through the innovative integration of VQE features with RadiSys Convedia media servers, conferencing service providers (CSPs) and their VoIP application development partners can address both IP media processing and VoIP quality improvements in a single network element. The integrated media server minimizes network complexity and CAPEX and OPEX costs, while improving audio quality for a broad range of VoIP and IMS services.
Next-generation conferencing architectures based on VoIP technology bring economic benefits with new feature capabilities for CSPs. However, they also present new technical challenges in maintaining acceptable voice quality. For CSPs, delivering good voice quality is an important requirement in their VoIP conferencing system, as poor voice quality could increase the costs associated with customer churn, while impacting the bottom line by reducing revenue growth opportunities.
RadiSys media servers with VQE technology cost-effectively overcome the sources of poor voice quality in IP packet networks. For multi-party VoIP conferencing services experiencing audio noise caused by background sounds or sub-optimal network and terminal equipment, VQE implements noise gating, noise reduction and noisy line detection mechanisms. VQE technology also includes packet loss concealment by intelligently restoring audio packets lost or unacceptably delayed by traffic congestion on the Internet. RadiSys Convedia media servers with VQE also remove acoustic echo by continuously monitoring all VoIP call legs, dynamically detecting echoes and selectively applying echo cancellation. Finally, all VQE features are supported with new audio and packet statistics, allowing CSPs to continuously measure audio quality for performance measurement and support SLAs with customers.
"Now that VoIP technology deployment has moved beyond early adoption to large production deployments, maintaining VoIP audio quality in large-scale networks has become a major focus among conferencing service providers," said Marc Beattie, Managing Partner, Wainhouse Research. "By integrating voice quality improvement capabilities within its Convedia media servers, RadiSys enables its customers to deliver dramatically improved call quality on a large scale."
RadiSys' integration of a comprehensive VoIP audio quality improvement package with existing IP media processing capabilities establishes an industry first among IP media server vendors. By consolidating both sets of real-time IP packet processing requirements in the same network element, RadiSys Convedia media servers with VQE improve audio quality, minimize end-to-end delay, streamline network integration and reduce CAPEX and ongoing OPEX costs through consolidated utilization of network equipment resources.
"As our conferencing service provider customers grow their VoIP network deployments, they have also expressed a desire for carrier-class solutions to address VoIP audio quality challenges," said David Smith, General Manager, RadiSys Media Server Business Unit. "Solutions to address VoIP audio quality, just like IP media processing for enhanced services, require sophisticated real-time IP media packet processing capabilities. Adding Voice Quality Enhancement is a natural addition to RadiSys Convedia media servers, and another innovative example of RadiSys applying its engineering expertise in solving real-world deployment issues for our customers."
