how do I restore the ringtone on my iphone

Please turn off the Caps Lock. It is not necessary and it is considered Rude. If your iPhone is not ringing, check the Mute switch on the side of the phone. If it is down towards the back of the iPhone and there is orange color showing, it is on Mute and will not ring. Also check the ringer volume on the phone and make sure that Focus is not set on Do Not Disturb. If the call not ringing is someone not in your Contacts, check Settings>Phone>Silence Unknown Callers is turned off.

You're welcome.
