Headset will not charge when connected to the USB port of a PC running Windows 8.1
Base firmware version 02.00, USB version 470
The mute function will now be available to use when the speakerphone is not in an active call. Users will be able to manually mute the microphone during music and media playback from the PC (streamed through the BT300 adapter to the Calisto P620) for a better audio experience. Note: Muting is not necessary when streaming music/multimedia from a mobile device.
A new feature, Local Mute, has been created for use with softphones that are not supported by Spokes.
Note: This update is available for PC only.
