Connecting a Device using a USB Cable

You connect your computer, mobile phone, or tablet directly to a Polycom Trio system using a USB cable that connects to the micro USB port on the system. When you connect your device to the system, you can use it as a microphone for calls and as a speaker for audio calls or media played on your device.

When you connect a Microsoft® Windows® computer to the system, you can control the volume of audio and video calls from the computer or on the Polycom Trio system. While connected, the call volume is synchronized on both devices.
