Yealink T42U
The SIP-T42U is a feature-rich business tool for superior communications and extended functionality. Equipped with numerous built-in soft keys, this 6-line IP phone ensures greater productivity. Combining Yealink Optima HD Voice technology with Opus' wideband codec, the T42U delivers exceptional audio quality and crystal clear voice communications. The phone feels faster and more responsive when using the calling features.
Simple customisation and high scalability
Equipped with two USB ports, the T42U is an efficient way to support your office by allowing you to use a Bluetooth, Wi-Fi or USB headset while recording via USB. You can also freely use these ports as needed to enhance the functionality of your phone. At the same time, the phone has three pages of flexible keys that are easily programmable with up to 15 paperless DSS keys.
HD Sound
Yealink's Optima HD voice technology combines state-of-the-art hardware and software with broadband technology for optimal acoustic performance. As a versatile and fully open audio codec, Opus is designed to produce higher quality HD audio than other broadband codecs over a high-speed network. However, if you have a poor quality network, Opus can provide better audio quality than other narrowband codecs. Its hearing aid compatible handset (HAC) helps people with hearing loss to hear voices more clearly.
