Easy customisation and high expandability

The SIP-T46S has two Gigabit Ethernet ports, one of which is suitable for Power over Ethernet (PoE). not only does the phone have three pages of flexible keys that can be easily programmed with a maximum of 27 paperless direct dialling keys, but up to three expansion modules can also be connected, providing up to 180 additional keys with a screen-based LCD display and LED system.

HD Audio

Yealink Optima HD Voice technology combines state-of-the-art hardware and software with wideband technology for maximum acoustic performance. Opus is a fully open, highly versatile audio codec and is designed to achieve higher HD audio quality than other wideband codecs at a high network bandwidth. However, if your current network quality is poor, Opus can give you better audio quality than other narrowband codecs. And its hearing aid compatible (HAC) handset helps people with hearing loss to hear the voice more clearly.

Efficient installation and deployment

Yealink's T4S series supports efficient deployment and effortless mass provisioning with Yealink's Redirection and Provisioning Service (RPS) and boot mechanism to enable zero-touch provisioning without complex manual settings, making the T4S series easy to deploy, maintain and upgrade. In addition, a unified firmware and Auto-P template that applies to all T4S phone models saves even more time and cost for businesses and simplifies management and maintenance.

Secure transport and interoperability

The Yealink T4S series uses SIP over Transport Layer Security (TLS/SSL), the latest network security technology. It is also compatible with leading soft switch vendors such as 3CX and Broadsoft Broadworks. In addition, it is equipped with two firmware images that provide you with enterprise-grade protection. Protection to prevent your system from malfunctioning after a failed upgrade.

Easy installation thanks to PoE

This network-enabled device is powered by Power over Ethernet (PoE) via the LAN cable. The main advantage of PoE is that you do not need a power supply cable. This allows you to install Ethernet-connected devices even in hard-to-reach places or in areas where a lot of cables would get in the way. You save installation costs and can increase the reliability of the connected devices by using a central uninterruptible power supply (UPS) if required.
