Hello,
Hmm, try these steps:
1) Restart the phone
2) If your phone has a case on it, remove it
3) Check for lint or debris around the mute button
4) Slide the mute button back and forth a few times
5) See this: How to put your iPhone on vibrate, ring, or silent mode - Apple Support
6) If no help, describe your exact symptoms in more detail
Good luck.
