Why would a headset not show up or take over a call?
When my iPhone 7+ iOS 10.1 is connected to my car via bluetooth and I'm on the phone, if I turn on my new headset (Insignia brand) the headset announces that it is on and connected to the phone, but does not show up on the phone as connected, and will not take over the call from the car, nor can I force it to. I can do this when using another headset.
When listening to music from the phone in the car, I can turn on this headset and it will automatically take over the audio.
The headset is a phone headset, it does work to make and receive calls.
