A Revolutionary SIP Phone for Enhancing Productivity
The SIP-T46S IP phone is the ultimate communications tool for busy executives and professionals. In addition to
offering better overall performance than the T46G, this device has a faster interface with a rich, high-resolution TFT
color display. Built with Yealink Optima HD technology and wideband codec of Opus, this device enables crystal clear
communications. The SIP-T46S is also built with Gigabit Ethernet technology, for rapid call handling and use with
accessories like a Bluetooth USB Dongle and a Wi-Fi USB Dongle. The new T4S series offers the same elegant
appearance of the T4 line, but with improvements for greater interoperability and collaboration.
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 Expandability
The SIP-T46S comes with two Gigabit Ethernet ports, one of which is suitable for Power
over Ethernet (PoE). A built-in USB 2.0 port can also be used for Bluetooth, Wi-Fi and USB
recording. The SIP-T46S supports up to six expansion models, for up to 240 additional
buttons with a screen-based LCD display and LED system. Plus, it has three pages of
buttons which can be programmed with up to 27 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-T46S 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
