DESIGNED FOR BUSINESS
The Yealink SIP-T43U is designed for professional users who need multi-line calling, extensive programmable controls and flexible accessory support without requiring a colour touchscreen.
Up to twelve SIP accounts can be configured, allowing the phone to support multiple extensions, telephone numbers or service providers where permitted by the connected platform.
Eight illuminated line keys can be assigned to SIP accounts, speed dials, Busy Lamp Field indicators, monitored extensions and platform-supported call functions.
Multiple display pages provide access to up to twenty-one programmable assignments without requiring printed paper labels.
The 3.7-inch 360 × 160 backlit display provides more room for caller information, line status, directories, call history and programmable-key labels than smaller T4U models.
Yealink Optima HD Voice combines professional acoustic hardware, wideband codecs and audio processing to support clear business conversations.
Acoustic Shield and Smart Noise Filtering help reduce unwanted background sound transmitted to the other caller.
A full-duplex speakerphone with acoustic echo cancellation allows both participants to speak naturally during hands-free conversations.
The hearing-aid-compatible handset uses a Hall-effect switch rather than a conventional mechanical hook switch, helping provide quiet and dependable operation.
Common call functions include hold, mute, transfer, forwarding, call waiting, Do Not Disturb, call pickup, call parking and voicemail access.
Five-way local conferencing allows several parties to be combined into one call, subject to firmware and telephone-platform configuration.
Directory support can include local contacts, remote XML phonebooks, LDAP and synchronised provider directories.
Dual Gigabit Ethernet ports allow the phone and a nearby computer to share one wired network connection without restricting the computer to Fast Ethernet speeds.
IEEE 802.3af Power over Ethernet allows a compatible network switch or injector to provide electrical power and network data through one Ethernet cable.
Where PoE is unavailable, the phone can use an optional compatible Yealink 5V/1.2A mains power adapter.
Two USB Type-A ports provide support for compatible USB headsets, USB storage devices and selected Yealink accessories.
USB call recording is supported when a suitable storage device, firmware and telephone-platform configuration are used.
Optional Yealink WF40 or WF50 adapters can add Wi-Fi connectivity where a wired network connection is unavailable.
Optional Yealink Bluetooth adapters support selected compatible wireless headsets and mobile-device connectivity.
Wi-Fi and Bluetooth are not built into the phone and require the correct optional USB accessories.
The dedicated RJ9 headset port supports compatible professional wired headsets using the appropriate connection cable.
Electronic Hook Switch support allows selected wireless headset systems to answer and end calls remotely when used with the Yealink EHS40 or another compatible solution.
The phone supports Yealink EXP43 colour-screen expansion modules for additional line, speed-dial, presence and Busy Lamp Field controls.
Up to three compatible EXP43 modules may be connected, subject to firmware and external power requirements.
The adjustable desktop stand provides two viewing positions and the phone can also be wall mounted using the appropriate accessory.
Yealink RPS, zero-touch provisioning and unified T4U firmware help simplify installation and management across larger deployments.
The phone requires a compatible SIP account, hosted VoIP service or IP-PBX configuration. These services are not included with the hardware.
