The SIP-T43U IP phone is a feature-rich business tool for excellent communications and extended functionality.  It is a 12-line IP phone that comes with a 3.7-inch large black-and-white screen and the EXP43 support. United  Yealink Optima HD Voice technology and wideband codec of Opus, the T43U awards you the superb audio quality and  crystal-clear voice communications. The phone feels quicker and more responsive when performing call features.  Moreover, the T43U puts dual USB ports in a phone that makes Bluetooth, Wi-Fi, USB headset and USB recording  come true, and you can use any two of them freely according to your needs. The Yealink new T4U series offers  the same elegant appearance as the T4 line, but with improvements for greater interoperability and better  collaboration.
