A:Answer It might be the iPhone. The latest iOS version has bluetooth issues. I bought an AT&T cordless phone system at Bestbuy that allows 2 cellphones to connect to via bluetooth. My Android phone works fine with it but my wife's iPhone 6 gets it's bluetooth disconnected soon as a call comes in. To troubleshoot I paired my company's iPhone 5S to the handset and had the very same issue. AT&T tech said it was an issue with iOS bluetooth, not their phone. I suggest trying a different phone, Android if possible just for trouble shooting purposes.
