The Yealink SIP-T74LTE redefines reliability in the world of office communications, offering for the first time in the Yealink Executive Series three independent and integrated communication paths in one device: Wired network via Gigabit Ethernet ports, wireless network via Wi-Fi, and cellular network via built-in 4G LTE.

This means that even if the entire LAN infrastructure goes down – whether due to a technical failure, internet outage, or natural disaster – the SIP Deskphone automatically switches to the 4G LTE cellular network and continues to operate without any manual intervention, ensuring continuity of vital communications under any circumstance.

The Yealink SIP-T74LTE features a 4.3-inch 480×272 pixel adjustable color touchscreen display that provides a smooth and intuitive smartphone-like interaction experience. The display clearly shows the current connection status and LTE signal level, giving the user and IT teams instant visibility into the status of all available connection paths.

This feature is vital for organizations that operate in critical environments, including financial and banking institutions that cannot tolerate interruptions, health facilities and emergency rooms, security operations centers, field offices and temporary locations that may not have a stable wired infrastructure, remote branches and regional offices with limited infrastructure, and crisis and disaster management facilities.

The Yealink SIP-T74LTE supports up to 16 SIP accounts with Yealink Acoustic Shield technology and advanced noise isolation for exceptional call quality across all communication paths.
