No sound when receive or make calls

Sometimes when I receive a call I can’t hear anything (except the ringtone) and the caller doesn’t hear me. I have to restart the phone to make it work. The same when I want to make a call. Can It have something to do with the fact that I shut down the sound during the night. Se screenshot. When I wake up I just adjust the sound again, screenshot 2. But it’s not like this everyday…strange! Any ideas?
