The Yealink SIP-T43U is the successor to the popular Yealink SIP-T42T and is equipped with a number of improvements and new features. The sound quality, for instance, has been improved considerably. The clear 3.7" LCD screen (360x160) ensures that all important information (such as the number and contact person) can be read at a glance

Fantastic HD sound quality

The sound of the Yealink SIP-T43U is taken to a higher level by the Opus codec. Opus delivers a higher HD audio quality than other codecs. The voice of your conversation partner therefore always comes across clearly and naturally. Another advantage of the Yealink SIP-T43U is that it is HAC (Hearing Aid Compatible), which makes the device also suitable for the hard of hearing.

USB connection

The two Yealink SIP-T43U integrated USB ports give you extra functionality. For example, you can connect a Bluetooth or WiFi dongle to the device to establish a wireless connection or to pair a wireless headset. You can use an external USB storage device to record local calls. This is handy if you want to listen back to calls.

PoE and headset connection

The Yealink SIP-T43U is equipped with two Gigabit (1000 Mbps) LAN connections with support for Power over Ethernet (PoE). With these connections, you can connect the device to a computer and supply power at the same time. You still need a PoE switch for this. There is also a headset connection (RJ9) with EHS support on the device. For example, a remote call can be accepted when using a wireless headset.
