Product information

Description

The Yealink SIP-T43U is a 12-line business IP phone with a 3.7-inch black-and-white display and support for the EXP43 expansion module. Equipped with Yealink Optima HD Voice and the Opus wideband codec, the T43U delivers clear voice communications and improved audio performance. The phone includes dual USB ports enabling Bluetooth, Wi‑Fi, USB headset and USB recording functions, and supports up to three expansion modules for additional programmable keys. The T4U series keeps the T4 line’s elegant design while enhancing interoperability and collaboration features.

Advantages

The device provides high-quality audio through HD voice technology and Opus codec, plus a hearing-aid-compatible handset. Dual USB ports allow flexible use of Bluetooth, Wi‑Fi, headsets and call recording without extra adapters. Programmable paperless DSS keys across three pages and support for up to three expansion modules increase functionality and scalability. Unified firmware and provisioning tools simplify mass deployment and maintenance.

  • Display: 3.7" black-and-white screen
  • Audio: Yealink Optima HD Voice; Opus wideband codec; HAC handset

How to use

Connect the SIP-T43U to your IP network and power it via PoE or the appropriate adapter. Use the phone’s web interface or provisioning service (RPS) to configure SIP account settings and apply the unified template if available.

Program the paperless DSS keys through the menu or web GUI and attach expansion modules if more programmable keys are required.

Recommendations

For best audio quality enable the Opus codec when supported by your SIP provider. Use Yealink’s RPS or auto-provisioning templates for large deployments to reduce manual configuration time. Keep firmware updated and retain the dual firmware images to avoid interruptions during upgrades.
