This is a wireless phone that is designed to do it all. It can handle conference calls, pair with Bluetooth devices and smartphones, provide excellent call quality while reducing background noise, and provides enough output noise to ensure that anyone listening in on the call will hear every word. The Yealink FCP930W Wireless HD Phone comes with a rechargeable battery that will give you 24 hours of total call time. And the battery will last longer when on standby. Not only that, it also serves as a makeshift speaker in case your smartphone or tablet is connected via Bluetooth. So, it does more than do conference calls, it can provide audio for presentations running off your smartphone or tablet when there are no speakers available. If that isn’t impressive, then what will?
