White Paper

Audio conferencing services based on circuitswitched networks and audio bridging equipment have provided hosted conferencing users with a benchmark for pricing and quality in voice communications. While next generation networks based on Voice over Internet Protocol (VoIP) technology introduce economic benefits with new feature capabilities for conferencing service providers (CSPs), they also present new technical challenges in maintaining acceptable voice quality. Delivering good voice quality is an important requirement in any VoIP conferencing system, as poor voice quality will increase the costs associated with customer churn, while impacting the bottom line by reducing revenue growth prospects.

Voice Quality Enhancement (VQE) encompasses an integrated set of features designed to overcome common audio quality problems in VoIP conferencing services, including noise, packet loss and echo. A comprehensive VQE solution also measures VoIP quality metrics, which are used in ongoing voice quality measurement associated with service level agreements.
