Yealink SIP-T44U Feature-Rich Business IP Phone
The Yealink SIP-T44U is a 12-line SIP desk phone with a 2.8-inch 320x240 backlit colour display, bringing colour-screen convenience to everyday business calling. Yealink Optima HD Voice with a full-duplex AEC speakerphone, Acoustic Shield, Smart Noise Filtering and a hall-switch handset hook keep calls clear and operation quiet.
Three Pages of Programmable Keys
Eight LED line keys programmable to 21 paperless DSS keys across 3 pages keep contacts and features one press away, and up to three EXP43 colour-screen expansion modules add up to 180 buttons for reception and attendant roles. Dual-port Gigabit Ethernet with IEEE 802.3af PoE (Class 3) keeps deployment to one cable.

Frequently Asked Questions — Yealink SIP-T44U
What is the difference between the Yealink T44U and T44W?
The T44W adds built-in dual-band Wi-Fi and Bluetooth 4.2; the T44U is wired-only but can gain Wi-Fi/Bluetooth via WF40/WF50 and BT40/BT41/BT51 USB dongles. Everything else — screen, keys, audio — is the same.
T44U or T43U — which should I choose?
The T44U has a 2.8" colour display; the T43U has a larger 3.7" greyscale display. Key counts match (21 DSS keys, EXP43 support), so it comes down to colour versus screen size.
Does the T44U support expansion modules?
Yes — up to three EXP43 colour-screen expansion modules for up to 180 additional buttons.
Does the T44U come with a power adapter?
The adapter is optional — it is designed for IEEE 802.3af PoE (Class 3, 2.0–4.9 W). For non-PoE desks, add the optional Yealink 5 V / 1.2 A PSU.
Which headsets work with the T44U?
RJ9 headsets (Yealink YHS34/YHS36), USB headsets such as the UH34, and wireless headsets via the EHS40 adapter.
Does the SIP-T44U come with a warranty in Singapore?
Yes. Every SIP-T44U sold by SourceIT comes with 2 years local Singapore warranty and a GST invoice.
