PRODUCT DESCRIPTION
Yealink SIP-T44W Feature-rich SIP Phone (1301213) - 2 Years Local Warranty
Yealink SIP-T44W Wi-Fi Business IP Phone
The Yealink SIP-T44W is a 12-line SIP desk phone with a 2.8-inch 320x240 backlit colour display and wireless built in: dual-band 2.4G/5G Wi-Fi (802.11a/b/g/n/ac, up to 433 Mbps) and Bluetooth 4.2, so it deploys anywhere without network cabling. Yealink Optima HD Voice with a full-duplex AEC speakerphone, Acoustic Shield 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 one press away, and up to three EXP43 colour-screen expansion modules add up to 180 buttons. Dual-port Gigabit Ethernet with IEEE 802.3af PoE (Class 3) covers wired desks with one cable.
Bluetooth for Headsets and Mobiles
Built-in Bluetooth 4.2 pairs Bluetooth headsets, syncs mobile contacts and handles Bluetooth calls, while two USB 2.0 ports add USB headsets and USB call recording — a flexible fit for hybrid desks across Singapore.
