The Yealink T53 IP Phone features an adjustable 3.7-inch graphical LCD that you can readily adjust it to a comfortable viewing angle. The SIP-T53 is coupled with the latest version of Yealink Optimal HD Voice technologies, including Yealink Acoustic Shield technology. This will effectively eliminate background distractions and noises and deliver crystal clear voice, even in a noisy environment. Meanwhile, complying with the latest Hearing Aid Compatibility (HAC) Regulations, its HAC handset helps people with hearing loss hear the voice more clearly. The Yealink T53W is a WiFi enabled version of this handset and is idea for use in areas where a direct wired internet connection is not convenient.

Wireless Transmission
The Yealink T53 IP Phone not only furnishes you with the Bluetooth connectivity, including Bluetooth headsets and mobile contacts synchronisation, when working with Yealink Bluetooth USB Dongle BT41, 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 the Yealink 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 to the corded-cordless phone via DECT technology. Moreover, the IP phone can function with Yealink VC Desktop together to share content from your laptop, making collaboration much easier than before.
High Expandability
A built-in USB 2.0 port allows you to enjoy USB call recording via USB flash drive. Via this USB port, you also can connect wired/wireless USB headset without connecting the Yealink EHS36, 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 realise the Zero Touch Provisioning without any complex manual settings.
