Designed for busy executives and professionals, the Yealink SIP-T53 IP Phone is an easy-to-use prime business phone with an adjustable 3.7-inch graphical LCD that you can easily and flexibly find a comfortable viewing angle according to your personal and environmental needs. This SIP-T53 ensures you to keep up with modern wireless technology and take the first chance in the future wireless age by working with Yealink Bluetooth USB Dongle BT40 and Yealink Wi-Fi USB Dongle WF40/WF50.

The phone's built-in USB 2.0 port allows for USB recording or a direct wired/wireless USB headset or up to three Yealink EXP50 expansion modules connection. Benefitting from these features, the Yealink SIP-T53 is a powerful and expandable office phone that delivers optimum desktop efficiency and productivity. As part of the T5 Series, this phone also effectively eliminates background distractions and noises and delivers a crystal clear voice even in a noisy environment.

• High Expandability - A built-in USB 2.0 port allows you to enjoy USB call recording via a USB flash drive. Via this USB port, you also can connect a wired/wireless USB headset without connecting Yealink EHS36 anymore, and connect up to 3 Yealink expansion modules EXP50 which can be programmed with up to 180 paperless DSS keys.
• Efficient Installation and Provisioning - The Yealink SIP-T53 supports efficient provisioning and effortless mass deployment with Yealink’s Redirection and Provisioning Service (RPS) and Boot mechanism to help you realize the Zero Touch Provisioning without any complex manual settings. Furthermore, a unified firmware and auto-p template that applies to T53/T53W/T54W/T57W phone models, saves even more time and costs for businesses, as well as simplifies the management and maintenance.
• User-Friendly - Yealink SIP-T53 IP Phone features an adjustable 3.7-inch graphical LCD that you can readily adjust to a comfortable viewing angle according to yourself. As to the audio quality, the SIP-T53 is coupled with the latest version of Yealink Optimal HD Voice technologies, including Yealink Acoustic Shield technology, which effectively eliminates background distractions and noises and delivers crystal clear voice even in a noisy environment. Meanwhile, complying with the latest Hearing Aid Compatibility (HAC) Regulations, its HAC handset helps the person who is with hearing loss to hear the voice more clearly.
• Wireless Transmission - Yealink SIP-T53 IP Phone not only furnishes you with Bluetooth connectivity, including Bluetooth headsets and mobile contacts synchronization, when working with Yealink Bluetooth USB Dongle BT40 but also the Wi-Fi connectivity when working with Yealink Wi-Fi USB Dongle WF40/WF50. Notably, you can access the 5G Wi-Fi connectivity handily if you use WF50. Also if you want to expand your horizons for busy environments, or, share one phone system with your small team by adding multiple handsets, just simply turn your IP phone into a corded-cordless phone via DECT technology.
