Product description

Wired desktop phone with professional features for high-definition communications

Yealink's T42U is a practical and versatile communication solution that adapts to the needs of all professionals. Designed for both intensive and occasional use, this phone can be used in three different ways to communicate: traditionally through the handset, on speakerphone when in a quiet space, or through a headset for hands-free operation in complete privacy. Take advantage of a powerful Wi-Fi connection by purchasing a WF40 or WF50 dongle, and opt for a Bluetooth connection by choosing a BT40 or BT41 dongle, which will give you more mobility.

Stylish and intelligent design 

The 2.4" LCD screen with a black and white display allows users to quickly see the date and time of day, the caller's name, number and connection status. Several LED indicators show incoming calls, messages waiting, and whether your employees' lines are available or busy. On the audio side, the Yealink T42U phone provides an immersive sound experience for users with full-duplex HD audio quality. AEC technology and acoustic shielding actively eliminate echoes and noise so that only voices from individual speakers are intelligible. Compatible with hearing aids, you can rest assured that you will be able to use this product without suffering from audio interference that can affect the quality of your conversations.

Multiple clever features

The Yealink T42U is a powerful telephone solution that allows users to make high-quality calls all day long. The 1000-entry phonebook allows you to store all the numbers you need, and the various programmable keys make it easy to create shortcuts to further simplify the day-to-day call handling process. This versatile device integrates numerous telephone functions such as call acceptance, call forwarding, call waiting, call transfer, and emergency calls. As a complete communication solution, this phone also includes additional features such as muting, auto-answer, or even intelligent dialing.
