Yealink T42U-CL IP Desk Phone

The Yealink T42U-CL is a six-line IP desk phone built for business communications. It features a 2.7 inch graphical LCD with 192 x 64-pixel resolution and backlight for clear visibility. Dual USB ports allow simultaneous connection of Bluetooth, Wi-Fi, USB headset or USB recording accessories. Power over Ethernet and Gigabit Ethernet provide flexible, high-speed network connectivity.

Suited for office users needing multiple lines

This phone suits professionals who handle several calls at once and want programmable keys for quick feature access. The adjustable stand and wall-mount option fit varied desk layouts. Buyers who require a colour display or integrated video conferencing should consider other devices. It is not a cordless handset or a mobile DECT solution.

Dual USB ports for peripheral flexibility

The two USB ports accept Yealink BT40 or BT41 Bluetooth dongles and WF40 or WF50 Wi-Fi dongles, plus USB headsets and recording drives. Any two functions can run together, letting you add wireless connectivity and a wired headset at the same time. This expandability defines the phone's adaptability to changing workflow needs.

Questions about this item

How do I connect the phone to the network and what step is often missed?

Connect the Ethernet cable to the LAN port for Power over Ethernet and data; the step often missed is securing the cable in the stand's routing channel so the desk stand sits flat at either adjustable angle.

Which accessories will need replacement first and how often?

The BT40 or BT41 Bluetooth dongle and WF40 or WF50 Wi-Fi dongle plug into the dual USB ports; they are the only moving parts and typically last several years before wear or loss requires replacement.

What limit appears first during long calls on the handset?

The 2.7 inch 192 x 64 LCD backlight stays on during calls, so the first limit is eye strain from the fixed 64-pixel height rather than any power or thermal constraint.
