I'm not sure this is the issue. The problem at its most fundamental is that the mic for voice telephony does not work. When I attach my BT or wired headset, I can speak to people, but when I switch the phone call to voice, whether connected to BT or wired, the mic does not work.
Can you use the mic for voice telephony at any time?
- when not connected to wired or BT headset ?
- when connected to either or both wired or BT headset (turn BT and speaker off)?
thanks
