AudioCodes announces VoIPerfectHD, its High Definition VoIP technology. High Definition VoIP delivers higher voice clarity, better intelligibility and richer sound, as well as significantly improving a user's experience by doubling the audible voice spectrum. AudioCodes plans to embed HD VoIP across its product portfolio throughout 2009.

Voice over IP emerged in the past 10 years as an alternative to traditional telephony. While providing lower cost and greater flexibility on converged voice and data networks, VoIP in general failed to deliver 'better-than-PSTN' quality mainly due to its 3.4 kHz bandwidth limitation connected with the use of legacy narrowband speech codecs in VoIP networks. With the advent and growing spread of IP broadband networks, wideband speech codecs which encode 7.1 kHz of the voice spectrum can now be effectively deployed to double the bandwidth and improve everyday voice communication quality to a level similar to that of conference room quality and/or FM radio. AudioCodes has been working over the past few years and increasingly in 2008 to implement a group of standards-based wideband speech codecs including G.722, AMR-WB, Microsoft RTAudio and others for use in wireline, wireless, cable, enterprise and internet applications with the goal of leading the transition towards increased use of HD VoIP in evolving voice communication networks.

AudioCodes VoIPerfectHD implementation of HD VoIP relies primarily on AudioCodes leadership in DSP, voice coding and voice processing technologies, and their application to VoIP communications and conferencing. AudioCodes VoIPerfectHD implementation as a unified infrastructure for all AudioCodes' products allows the offering of HD VoIP capabilities and benefits across all of its products ranging from Multi-Service Business Gateways, Media Servers, Media Gateways and DSP chips to IP Phones.

The introduction of HD VoIP extends AudioCodes reach to both enterprises and service providers, allowing entry into new market segments which will benefit from enhanced clarity and better speech intelligibility. Among key segments expected to benefit from this new introduction are banks, government, military, health, telemedicine and education. AudioCodes' HD VoIP is designed to enable enterprises to improve worker collaboration resulting in higher productivity and enhanced customer service quality. Service providers are expected to benefit from differentiating their VoIP offering and services by increasing call length and having a higher Average Revenue per User. In addition, application providers and ISVs are capable of effortlessly enhancing their solutions in order to meet stringent voice quality standards.

AudioCodes' current and planned HD VoIP Enabled products consist of the IPmedia 3000 Media Server, Mediant 3000 Media Gateway, Mediant 1000 MSBG and the Mediant family of Microsoft certified basic Hybrid Gateways. AudioCodes' Media Servers and Gateways now enable transcoding between different wideband coders while retaining wideband quality. This will allow interworking and connectivity between different wideband networks such as mobile and broadband. AudioCodes plans to introduce HD VoIP on more products in 2009.

AudioCodes has created a website landing page www.audiocodes.com/hdvoip which includes all technical and marketing resources for the HD VoIP.
