iPhone 6 does not make sound when paired with headset
I use an iPhone 6 with a bluetooth-connected Plantronics Voyager headset. When the phone is paired with the headset, none of the iPhone sounds (like email arriving, text arriving, other alerts, etc.) sound through the phone - the sound is only through the headset. Sometimes I'm waiting for a call for 3 or 4 hours and don't want to wear the headset the whole time just to get the other sounds, so I take it off - but then I miss the alerts.
Is there any way to have the iPhone 6 provide the audible sounds even when paired to the headset?
Thanks.
