High Definition VoIP (HD VoIP)

High Definition VoIP (HD VoIP) - Market Requirements

In the past 10 years, Voice over IP has emerged as an alternative to the traditional Telephony (PSTN) allowing a reduction in costs and increased capacity on long-distance telephone calls. While providing for lower costs and greater flexibility on converged voice and data networks, VoIP in general failed to deliver ‘better-than-PSTN’ quality, mainly due to the 3.4 Khz bandwidth limitation of legacy narrowband speech codecs. Capitalizing on expanding IP broadband networks, wideband speech codecs which encode 7.1 Khz of the voice spectrum can now be effectively deployed in VoIP. This enables the doubling of bandwidth for voice communications, allowing the elevation of daily voice communication to be similar to that of FM radio and/or conference room quality.
