Lifesize® Phone™ HD

Lifesize HD Video Conferencing

Lifesize Phone HD puts the power to control HD video and collaboration at your fingertips


With Lifesize Phone HD, you can manage Lifesize Cloud video and audio calls and web conferences, making it easier than ever to collaborate with colleagues and partners. Lifesize Phone HD features an intuitive touchscreen interface that is simple enough for anyone to use, so more people will want to use it every day.

The Lifesize Phone HD replaces the 2nd Generation Phone and has a larger, dramatic new interface that provides rapid access to the most popular features. The UI is inspired by the best UIs in the mobile space, customer testing and market feedback (you spoke; Lifesize listened).

Advanced beam-forming algorithm steers the microphones to the location of the talker for greater voice pickup and reduced room noise. There’s no need to huddle over the phone or move the phone during calls.
