12-Line SIP Phone with 2.8-Inch Color Display, Dual USB 2.0 Ports for Bluetooth and WiFi Adapters, Hall Switch, PoE, and EXP43 Expansion Module Support
The Yealink SIP-T44U (1301214) is a 12-line IP phone with a 2.8-inch color display at 320x240 resolution, dual USB 2.0 ports that support Bluetooth adapters, WiFi dongles, USB headsets, and call recording simultaneously, and Yealink Optima HD Voice with Opus codec for superior audio clarity across varying network conditions. Dual-port Ethernet with built-in PoE provides wired connectivity with PC passthrough and powers the phone directly from the network switch.
The SIP-T44U brings the T4U series' dual USB architecture and color display into a compact, cost-effective 12-line desk phone. The integrated Hall Switch provides smooth, quiet handset cradle operation for professional environments. The phone connects up to three EXP43 expansion modules for up to 180 additional programmable keys, registers with standard SIP-based PBX platforms, and deploys through Yealink's Redirection and Provisioning Service for zero-touch provisioning with unified T4U firmware across the entire series.
