12-Line SIP Phone with 3.7-Inch Graphical Display, Dual USB 2.0 Ports for Bluetooth and WiFi Adapters, PoE, and EXP43 Expansion Module Support
The Yealink SIP-T43U (1301202) is a 12-line IP phone with a 3.7-inch graphical LCD at 360x160 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-T43U sits in Yealink's T4U series, upgrading the previous T4S generation with dual USB ports, Opus codec support, and dual firmware images for failsafe upgrades. The dual USB ports set the T43U apart by enabling any combination of two accessories at once, from a BT41 Bluetooth adapter and WF50 WiFi dongle to a USB headset and flash drive for call recording. 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.
Where the SIP-T43U Fits
- Multi-line office environments where 12 SIP accounts handle calls for multiple departments or routing configurations on a single phone, dual USB ports add Bluetooth headset pairing and WiFi connectivity through adapters, and 21 programmable DSS keys across three pages provide speed dial, BLF, and custom function assignments
- High-volume reception and call center desks where up to three EXP43 expansion modules add up to 180 programmable keys with LCD display and LED indicators for BLF monitoring, speed dial, and line management across large call environments
- Managed SIP phone fleets where unified T4U firmware simplifies provisioning across all T4U models, zero-touch provisioning through Yealink's RPS and Boot mechanism handles deployment without manual configuration, and dual firmware images provide enterprise-level protection against failed upgrades
What the SIP-T43U Delivers
- 3.7-Inch Graphical LCD: 360x160 resolution graphical display with backlight provides visual call management, directory search, and line status for up to 12 SIP accounts. Three pages of 21 programmable DSS keys use paperless labels for speed dial, BLF, and custom function assignments.
- Dual USB 2.0 Ports: Two USB ports support any combination of two accessories simultaneously, including BT41 Bluetooth adapter for wireless headset pairing, WF40/WF50 WiFi dongle for wireless network connectivity, USB headset for hands-free operation, and USB flash drive for call recording.
- 12 SIP Accounts with Optima HD Voice: Registers up to twelve independent SIP lines for multi-department call handling on a single phone. Yealink Optima HD Voice with Opus codec delivers wideband audio that adapts to network bandwidth for clear conversations on any connection quality.
- PoE with Dual Ethernet: Dual-port Ethernet with PC passthrough and built-in PoE for single-cable installation from the network switch. SIP over TLS/SSL provides secure transport for enterprise environments.
- EXP43 Expansion Module Support: Connects up to three Yealink EXP43 expansion modules for up to 180 additional programmable keys with LCD display and LED indicators for BLF, speed dial, and custom function assignments at reception desks and high-volume call environments.
Does the Yealink T43U Have Wi-Fi?
The SIP-T43U does not include built-in WiFi, but its dual USB 2.0 ports add wireless network connectivity through Yealink's WF40 or WF50 USB WiFi dongle. The dual USB design allows a WiFi dongle and a second accessory to operate simultaneously, so the phone can connect wirelessly while also using a Bluetooth adapter, USB headset, or USB flash drive for call recording through the second port.
