When Using the Internet to Make Calls, Callers Can't Hear Me
If when using the internet to make calls (i.e., using VoIP), callers cannot hear you:
Check that the application being used has "Plantronics Wireless Device" listed as the active device for listening and speaking.
Some applications need to be set manually or restarted before they will recognize a new audio device.
NOTE: In unusual circumstances the headset may switch off. Switch the headset back on to resume normal operation.
