Yealink SIP-T73U Datasheet

Multifunctional SIP Phone, Excellent Voice Communication


The T73U IP phone is an all-in-one business phone that enables excellent voice communications and extended functions. Equipped with Hall switch technology, the T73U provides you with a quieter office environment. The redesigned appearance of Yealink's new T73U makes the phone more fashionable, thinner, and more in line with modern aesthetic standards. The T73U supports 12 SIP account registrations and is equipped with a 2.8-inch color display, backlight, and an EXP55 expansion station. Combined with Yealink 's ultra-high-definition voice technology, the T73U provides excellent audio quality and clear voice communications. When making calls, the phone responds faster and more responsively.

In addition, a built-in USB port realizes the functions of a USB headset and USB recording, and you can choose freely according to your needs. The T73U adopts a TEE hardware encryption solution, providing you with a more secure storage experience. At the same time, it improves the phone's performance, 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 configuring and upgrading headsets through LCD and supports Yealink headsets with a wearing detection function for intelligent channel switching.

HD Audio Ultra-High-Definition Sound Quality

The sound quality of Yealink T7X series phones is higher definition and perfect, making communication easier. Yealink combines cutting-edge hardware and software with broadband technology to achieve the best acoustic performance. Its hearing aid compatible (HAC) handset helps people with hearing loss hear sounds more clearly.

High Security and Compatibility

T73U adopts the latest TLS/SSL network security technology. It is widely compatible with leading soft switch vendors, such as 3CX, Broadsoft, and Broadworks. In addition, T73U 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. T73U supports the security center function, allowing users to decide whether to connect the phone to the device management platform/service and what private data is allowed to be reported.

Customizability and Scalability

T73U supports five-page page turning and up to 40 programmable buttons. In addition, T73U can be cascaded to up to 3 expansion units. 234 programmable buttons effectively save operation time and achieve efficient office work.

Easy Installation and Deployment

You can use Yealink RPS (Redirection and Provisioning Service) and Boot mechanisms to enable 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 be automatically deployed, saving a lot of time and cost, and achieving true "zero-touch provisioning". In addition, Yealink T7X series IP phones all use the same firmware, which greatly simplifies management and maintenance costs and facilitates management, upgrades, and maintenance.

TEE Hardware Encryption Solution

T73U uses the TEE hardware encryption solution, which can provide you with a more secure data storage experience.
