A Groundbreaking SIP Phone for Increasing Productivity:- The Yealink SIP-T46U IP Phone, designed for busy executives and professionals, is an ultimate communication tool with superior overall performance. The phone has an eye-catching high-resolution TFT color display that appears brighter and more vibrant. The T46U provides superb audio quality and crystal-clear voice communications by combining Yealink Optima HD Voice technology and Opus’ wideband codec. Furthermore, the T46U includes dual USB ports in a phone, enabling Bluetooth, Wi-Fi, USB headset, and USB recording, and you can use any two of them freely depending on your needs. The T4U series from Yealink has the same elegant appearance as the T4 line, but with improvements for greater interoperability and collaboration.

Key Features and Advantages

Simple Customization and Extensibility:- The SIP-T46U has two Gigabit Ethernet ports, one of which supports Power over Ethernet (PoE). The T46U is your right-hand man in the office, with two USB ports that enable Bluetooth, Wi-Fi, USB headset, and USB recording, and you can use any two of them freely to enhance phone features. Meanwhile, the phone not only has three pages of flexible buttons that can be easily programmed with a maximum of 27 paperless DSS keys, but it also has the ability to connect up to three expansion modules, for a total of 180 additional buttons with a screen-based LCD display and LED system.

Hi-Definition Audio:- For maximum acoustic performance, Yealink Optima HD Voice technology combines cutting-edge hardware and software with wideband technology. Opus, as a completely open, highly versatile audio codec, is designed to provide better HD audio quality than other wideband codecs in high network bandwidth; however, if your current network quality is poor, Opus can provide better audio quality than other narrowband codecs. Furthermore, its hearing aid compatible (HAC) handset allows people with hearing loss to hear the voice more clearly.

Installation and provisioning that is efficient:- Yealink’s Redirection and Provisioning Service (RPS) and Boot mechanism enable efficient provisioning and effortless mass deployment, allowing you to achieve Zero Touch Provisioning without any complex manual settings, making the T4U series simple to deploy, maintain, and upgrade. Furthermore, a unified firmware and auto-p template that applies to all T4U phone models saves businesses even more time and money while also simplifying management and maintenance.

Transport Security and Interoperability:- The Yealink T4U series employs the most recent network security technology, SIP over Transport Layer Security (TLS/SSL). It’s also compatible with leading soft switch vendors like 3CX and Broad soft Broad works. Furthermore, it comes with dual firmware images, which provide enterprise-level protection against bricking your system if the upgrade fails.
