iPhone won't make call with OnStar
I hope someone will be able to help me. I have an iPhone 5s and a 2011 Chevrolet equinox. Until recently, I had no problems. Several months ago, the phone feature stopped working through The Bluetooth system. I can tell Siri to place the call by using Bluetooth, but when it actually starts the call, the Bluetooth disconnects and I have to use the phone.I have tried simply dialing a phone number hoping that the Bluetooth would pick it up, When someone calls me, the phone rings through the speaker system, clearly through the Bluetooth link, but when I answer the phone, the Bluetooth disconnects. I was on the old operating system, but I upgraded to 8.1.2 to see if I could fix it. It did not help. I have deleted the link to the phone and re-sync to my phone several times.I truly hope there's someone out there who can tell me which magic button I'm missing because you will make my day! Thank you to all who have read this and anyone who is willing to help me.
iPhone 5s, iOS 8.1.2
