HD (High Definition) Voice

Benefit from crystal clear conversations.

HD (High Definition) Voice, also know as Wide-band Audio, extends the frequency range of sound travelling over a phone conversation, resulting in higher quality voice. The range of the human voice extends from 80 hertz to 14,000 hertz. Traditional, or narrow band telephone calls, limit audio frequencies to the range of 300 to 3400 hertz. HD Voice opens up that range to be between 30 hertz to 7000 hertz.

This HD phone feature allows for phone conversations that are crystal clear and easily understood. You never have to worry about missing important pieces of information again. HD Voice makes your phone conversations more enjoyable and completely stress-free.
