Silent switch turned on? Do Not Disturb? Ringer volume down?

Re: Why my iphone 5s isn't ringing

I have a similar problem at home. I have a relatively weak voice signal from T-Mobile and even with Wifi on strong, sometimes I get a missed call indication when the phone was only two feet from me and never rang. Also happens with iPhone 6. Other phones (BlackBerry, Samsung) have worked fine under the same conditions.
