Multifunctional SIP Phone, Excellent Voice Communication

The T74W IP phone is a high-end color screen business phone designed for management and professionals. It has a more business-like appearance and a high-definition TFT color screen, giving users a lifelike visual experience. The redesigned appearance of Yealink’s new T74W makes the phone more fashionable, thinner, and more in line with modern aesthetic standards. Yealink T74W uses a Hall switch handset to make the office environment quieter. At the same time, T74W has ultra-high-definition, gorgeous sound quality and supports broadband audio codec, providing users with realistic audio call effects. In addition, T74W has a built-in Bluetooth 5.0 module and dual-band 2.4G/5G Wi-Fi 6 modules, allowing you to keep up with the latest technology and gain an advantage in the future wireless era. T74W supports a USB 2.0 interface, USB headset, and USB recording functions; you can choose according to your needs. The T74W adopts a TEE hardware encryption solution, providing you with a more secure storage experience. At the same time, it improves the performance of the phone, bringing you more flexible interoperability and a better collaboration experience. The T7X series better builds the Yealink ecosystem and is compatible with more Yealink headsets. The phone supports headset configuration and headset upgrades through LCD and supports Yealink headsets with a wearing detection function for intelligent channel switching.

Ultra-HD Sound Quality

The Yealink T7X series phones offer higher definition and superior quality, making communication easier. To ensure user comfort during long calls and effective hearing protection, Yealink has carefully created an ultra-high-definition sound quality solution from the handset, speaker, hands-free, and sound cavity. The sound coding format supported by T74W, as a completely open and highly versatile audio codec, provides higher-definition audio call quality and a better voice call experience compared to other narrowband codecs, even when the phone network is unstable. Additionally, T74W uses the HAC handset to help people with hearing impairments use the phone better.

High Security and Compatibility

T74W adopts the latest network security technology, supporting SRTP and TLS call encryption, 802.1x media access control, MD5 and MD5-Sess-based authentication, AES security profile, and other perfect security protection mechanisms to avoid hacker attacks. It is widely compatible with third-party SIP devices and leading SIP platforms. In addition, T74W supports a dual system function, which can back up your phone system in advance to avoid system crashes caused by upgrade failure, thus providing you with enterprise-level system protection. The T7X series also supports a security center function to ensure your phone is more secure, with high-sensitivity functions and data supporting user individual control and one-click disconnection.

Customizability and Scalability

T74W not only has Gigabit PoE dual network ports for PoE power supply but also features a USB port for easy integration with USB headsets and USB recording. You can choose based on your needs. T74W supports five pages of page turning and can accommodate up to 50 programmable buttons; in addition, T74W can cascade up to 3 color screen expansion units, expanding to 234 programmable buttons to save operation time and achieve efficient office work effectively.

Easy Installation and Deployment

You can use Yealink RPS (Redirection and Provisioning Service) and the Boot mechanism to achieve fast and efficient deployment. Users do not need to manually configure and upgrade the phone. They only need to power on and connect to the Internet, and the phone will complete automatic deployment, saving a lot of time and cost, and achieving true “Zero Touch Provisioning.” In addition, Yealink T7X series IP phones (including T73U, T73W, T74W, and T74U) all use the same firmware, which greatly simplifies management and maintenance costs and facilitates management, upgrades, and maintenance.

Wireless Data Transmission

Yealink T74W has a built-in Bluetooth 5.0 module, supports Bluetooth headsets, and can connect to mobile phones via Bluetooth for phone address book matching. To adapt to the upcoming 5G Wi-Fi era, T74W has built-in dual-band Wi-Fi 6. 5G Wi-Fi offers better anti-interference and faster speed, allowing you to be one step ahead in the busy data torrent. Additionally, T74W can be used with the Yealink video conferencing soft terminal to share content from the computer to the remote end, providing the ultimate content-sharing experience.
