It’s available in standard UC or Microsoft Teams editions with either USB-A or USB-C connectivity via a USB cable that wraps around the speakerphone neatly when not in use. Every model supports Bluetooth to connect with a smartphone or tablet. There are also versions with USB-A or USB-C Bluetooth dongles included to use the speakerphone wirelessly with a computer or laptop.
