How to set up the PC USB Audio Feature on a Poly CCX 600 Phone

The Poly CCX 600 is a top-of-the-line elegantly designed desk phone with a touch-screen and 7-inch display with high-end features that is available as both a SIP Desk Phone and a Microsoft Teams Desk Phone.

The Poly CCX 600 lets you connect your phone to a computer and configure it as an external audio device in USB audio mode.

The PC USB Audio function uses your Poly CCX 600 phone in Microsoft Teams or generic mode as a USB audio device for your PC or Mac. The Poly CCX series has built-in Acoustic Fence and NoiseBlock AI technologies and gives you the flexibility needed for working from home, hot-desking on-site, or quick calls from focus rooms. No software is needed. (Please note that the USB Audio mode requires your phone to be running firmware version 7.2.0 or higher.)

Before you begin, ensure that the phone is plugged into a power source. The phone cannot be powered through a USB cable.

You will also need a USB cable with USB-C on one end and a USB connector that is compatible with your computer on the other end. This may be a USB-A or USB-C connector depending on your computer.

Follow these steps to setup USB Audio:
– Connect the USB-C end to the top USB-C port on your phone
– The lower USB port can be used as a host port for headsets or USB adapters
– Then connect the other end of the USB-C cable to your computer
– When you enter a call on your computer, your Poly CCX phone will appear as an audio option

  • If I connect my CCX 500 to my PC in USB audio mode, would I be able to initiate a call on PC Teams client and then utilize the handset on the CCX 500 for more privacy, or is connection to CCX 500 limited to speakerphone mode?

    • Hi Mark,

      You can utilize that CCX 400, 500, 600 that includes the handsets for all three. You can have a speakerphone on, a USB headset plugged in and USB-C audio to PC USB-A or USB-C. Via the PC settings the phone's mic provides the audio input to the PC and the phone's speakerphone plays the computer audio output. You can pick up the handset and the CCX will default to handset mode. You basically can toggle the audio on the device with the devices connected.
