Can anyone tell me if the call volume can be boosted from standard on the iPhone 6?  I don't mean through jail breaking but an official Apple fix.  My problem is that I am a hearing aid user and the calls are barely audible even in a quiet environment so took it back to the Apple Store and was told that it was not possible to increase the volume and they didn't even test it.  I don't believe this for a second but just need to confirm if it is possible before I take the matter further.  I had no problems with volume on the iPhone 4 and on my Galaxy S4 I even had to turn it down at times!
