An Affordable SIP Phone for Clear Communications

Overview

The SIP-T41S is a feature rich business tool for superior communications and extended functionality. It offers a faster, more responsive interface than the T41P and several performance enhancing functions.

It’s a six line IP Phone that comes with built in programmable keys to enhance productivity. The SIP-T41S with Yealink Optima HD Voice technology and wideband codec of Opus delivers superb audio quality and crystal clear voice communications.

With an all-new USB port, the SIP-T41S boasts unparalleled functionality and expansibility with Bluetooth, Wi-Fi and USB recording features. The Yealink’s new T4S series offers the same elegant appearance of the T4 line, but with improvements for greater interoperability and collaboration.

Key Features and Benefits

HD Audio

Yealink Optima HD Voice technology combines cutting-edge hardware and software 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.

Easy Customization and High Expansibility

With an all-new USB port, the SIP-T41S is your ideally powerful and expandable office phone with Bluetooth, Wi-Fi and USB recording features. It has three pages of flexible buttons which can be programmed with up to 15 paperless DSS keys.

Efficient Installation and Provisioning

The Yealink T4S series supports efficient provisioning and effortless mass deployment 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 auto-p 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 management and maintenance.

Secure Transport and Interoperability

The SIP-T41S uses SIP over Transport Layer Security (TLS/SSL), which is the latest network security technology. It’s also compatible with leading soft switch suppliers 3CX and Broadsoft Broadworks.
