The Yealink SIP-T42S is the successor to the popular Yealink SIP-T42P and is equipped with a number of improvements and new functionalities. For example the sound quality has improved considerably. The clear 2.7 "LCD screen (192x64) 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-T42S 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 as clear and true to nature. Another plus of the Yealink SIP-T42S is that it is HAC (Hearing Aid Compatible), which makes the device also suitable for the hearing impaired.

USB connection

New to the Yealink SIP-T42S is the integrated USB connection with which you can add additional functionalities. For example, 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 for local call recording. Handy if you want to listen back to conversations.

PoE and headset connection

The Yealink SIP-T42S is equipped with two Gigabit (1000 Mbps) LAN connections with support for Power over Ethernet (PoE). With these connections you can daisy-chain 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.
