PRODUCT DESCRIPTION
Yealink SIP-T34W Classic Business Colour Wi-Fi IP Phone (SIP-T34W) - 1 Year Local Warranty
Colour Screen, Four Lines, Wireless Freedom
The Yealink SIP-T34W is the wireless flagship of Yealink’s classic T3 series: a 2.4-inch 320 x 240 colour display, four SIP accounts, built-in dual-band 2.4G/5G Wi-Fi (802.11a/b/g/n/ac) and a USB 2.0 port for headsets. It deploys anywhere in the office without an Ethernet drop.
Built for Busy Desks
Four LED line keys programmable up to 12 paperless DSS keys handle busy small-office calling, while WPA2/WPA3-secured Wi-Fi removes cabling constraints. HD voice with a full-duplex AEC speakerphone keeps calls clear, and dual-port Gigabit Ethernet with PoE remains available for wired desks.
USB and Wireless Headset Ready
The USB port supports Yealink wired USB headsets and Bluetooth headsets via Yealink BT50/BT51A adapters, alongside the RJ9 port with EHS wireless headset support — flexible options for hybrid workers and call-heavy desks.
