The Cisco Unified Wideband Handset significantly enhances the Cisco Unified IP phone communications by providing a clearer and richer audio experience. This handset provides an audio frequency response that is more than double when compared to the traditional narrowband audio used on most of today's telephones. The result is an enhanced audio experience that makes communications a more intelligible and more comfortable user experience. This handset is sold as an add-on accessory that can be installed to many Cisco Unified IP phone models. And when combined with the G.722 Wideband codec, the result is a superior audio experience.
