iPhone 5 Outgoing call-no audio
Hi all. I am new to the Apple forums. I have a problem with my iPhone 5. On calls, the audio doesn't work at all. I cant hear anything and neither can the other person. Audio and microphone work in all other apps just not the phone app. I have tried so many things from hitting the back of the phone to restoring it in iTunes several times. I have also tried getting a new simcard and that didnt work either. I am in desperate need of help. Thanks!
