Product description

Feature-rich 6-line VoIP phone

Introducing the Yealkink SIP-T41S, a feature-rich 6-line desktop VoIP phone. It comes with a high resolution 2.7" backlit graphical display as well as a wide range of advanced productivity-enhancing features. Part of Yealink´s 4 series, the integrated IEEE 802.3af Power Over Ethernet (PoE) ensures easy deployment with centralised power and back up. As a result, this phone does not come with a power supply although this can be purchased separately. This phone has been designed for professionals who require multiple lines, supporting up to 6 SIP accounts. It is easy and comfortable to use and its stand can be adjusted into 2 angles.

Features Optima HD technology

Firstly, Yealink SIP-T41S comes with Optima HD technology, which combines market-leading hardware with wideband technology which in turn ensures optimal acoustic performance. What´s more, this VoIP phone also supports the Opus audio codec, Opus provides a greater HD audio quality and a more crystal clear voice sound than other wideband codecs in high network bandwidth. Even if your network quality is poor, rest assured that your calling quality will not be affected. With Opus, enjoy clearer conversations than you would by using other narrowband codecs. If this wasn't enough, the SIP-T41S also has a hands-free speakerphone with echo cancellation. Take your important calls while ticking other tasks off your to-do list.

Effortless customisation and expansion

With a USB port, the SIP-T41S comes with Bluetooth, Wi-Fi and USB recording features. Not to mention, it features three pages of flexible buttons. The flexible buttons can be programmed with up to 15 paperless DSS keys. Whatever you require, customise your VoIP phone to suit your needs.

Seamless installation and provisioning

Thanks to Yealink`s Redirection and Provisioning Service (RPS) and Booth mechanism, deployment and management of your device will be a breeze. What`s all T4S phone models use a unified firmware and auto-p template. In turn, save your business extra time and money. This also helps to simplify maintenance and management.

Security first

Also, the SIP T41S uses the latest network security technology, which is called SIP over Transport Layer Security (TLS/SSL). Not to mention, it is compatible with market-leading soft switch suppliers, 3CX and Broadsoft Broadworks.
