PRODUCT DESCRIPTION
Yealink SIP-T34W Classic Business IP Phone (1301037) - 2 Years Local Warranty
Yealink SIP-T34W Colour Wi-Fi Business IP Phone
The Yealink SIP-T34W is the wireless flagship of Yealink’s classic T3 series: a 2.4-inch 320x240 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 while keeping calling fully professional.
Colour Screen, Four Lines, Wireless Freedom
Four LED line keys programmable to 12 paperless DSS keys handle busy small-office calling, while WPA2/WPA3-secured Wi-Fi removes cabling constraints. Yealink HD voice with a full-duplex AEC speakerphone and Smart Noise Filtering keeps calls clear; dual Gigabit Ethernet with PoE remains available for wired desks.
USB Headset Ready
The USB port supports Yealink wired USB headsets and Bluetooth headsets via BT50/BT51A adapters, alongside the RJ9 port with EHS support — flexible options for hybrid workers and call-heavy desks in Singapore.

Frequently Asked Questions — Yealink SIP-T34W
What is the difference between the Yealink T34W and T31W?
The T34W adds a 2.4" colour screen (vs greyscale), 4 SIP accounts (vs 2), 12 programmable DSS keys, Gigabit Ethernet (vs 10/100) and a USB headset port. Both share the same built-in dual-band Wi-Fi. See the SIP-T31W for the budget option.
Does the T34W have built-in Bluetooth?
No. Bluetooth headsets are supported via the optional Yealink BT50/BT51A USB adapter; the datasheet lists no built-in Bluetooth radio.
Can I use USB headsets with the T34W?
Yes — its USB 2.0 port supports Yealink wired USB headsets such as the UH34, alongside the RJ9 port with EHS wireless-headset support.
How is the T34W powered on a Wi-Fi-only desk?
Use the included DC 5 V power adapter. On wired desks, IEEE 802.3af PoE (Class 2, 2.33–3.35 W) powers it over one cable.
T34W or T33G — which should I buy?
Choose the T34W for Wi-Fi deployment and USB headset support; choose the SIP-T33G if the desk is wired and you want the lowest-cost 4-line colour phone.
Does the SIP-T34W come with a warranty in Singapore?
Yes. Every SIP-T34W sold by SourceIT comes with 2 years local Singapore warranty and a GST invoice.
