iPhone 5 does not ring but calls come through (silently)

[biznet]

My iPhone does not ring. I just noticed it today while working from home and I am not sure if I missed any at work. I was scolded by friends before for not responding to their calls so I am guessing it happened before as well.I can see the incoming call on the screen but without the ring tone. I checked all the settings and found no problems. I am using 6.1.2 ios version. Any ideas or suggestion to try?
