with wideband 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 wideband 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 narrowband
codecs. And its hearing aid compatible (HAC) handset helps the person who is with
hearing loss to hear the voice more clearly.

with Yealink’s Redirection and Provisioning Service (RPS) and Boot mechanism to help
you realize the Zero Touch Provisioning without any complex manual settings, which
makes the T4S series simple to deploy, easy to maintain and upgrade. Furthermore, a
unified firmware and autop template that applies to all T4S phone models (T41S, T42S,
T46S and T48S), saves even more time and costs for businesses, as well as simplifies the
