HD Audio Features

YeaLink Optima HD Voice technology combines cutting-edge hardware and software with wide band technology for maximum acoustic performance. Being a totally open, highly versatile audio codec, Opus, is designed to perform a higher HD audio quality than other wide band codecs in a high network bandwidth.

However, if your current network quality is poor, Opus can provide you with a better audio quality than other narrow band codecs. And its hearing aid compatible (HAC) handset helps the person who is with hearing loss to hear the voice more clearly.
