First thing you do is make call then check to see if the mute is on! Push voice/mute button found on underside of mic boom. Till you hear it say mute on or mute off then try call again when you have comfirmed that mute is off.
The issues with the Voyager Edge is one where the problem is when the microphone is used in call it malfuntions but if you use the voice command it will work just fine you can do the same with the voice assistant if you make a call from the voice assistant the person your calling should be able to hear though it might not be as clear but more then enough for you to be heard by person you are calling.
This is just a temporary solution the real issue is that there is a bug in the hardware and as yet to be resolved by any other means than to send defective unit back to plantronics and have them replace the unit and tell them about the issues with unit you encountered.
I will be sending in my own Voyager Edge SE with microphone malfuntion in call and the OTG (On The Go) you need an OTG conector/adaptor to test this feature is malfunctioning so cant be updated.
