iPhone 5 goes straight to voicemail when connected to Bluetooth
When my iPhone 5 is connected to Bluetooth in the car it won't receive calls; callers go straight to my voicemail. There are no problems making calls, or streaming music via Bluetooth in the car, just receiving calls. When not connected to Bluetoth, receiving calls is no problem. I tried going through settings and accessibility and changing the Bluetooth setting to "Headset" but that didn't change anything. Also, I tried looking for the latest software and get the message that my OS is up to date. It used to work fine, but something has obviously changed....
iPhone 5, iOS 9.2.1
