Try to force restart your phone(power button+vol up until the phone vibrates).It should work if you press volume down.
I was suggesting a forced restart to see if after the silencer works fine.
Yes,to silence you need to press vol down.To force restart(power button+vol up until the phone vibrates).But first try to silence.

Ok so I'm sure this happens to people all the time so hopefully theirs an answer to this... So in part phones whenever my phone would go off (ringtone) and I was in an environment where my ringtone isn't suitable I would just press the power button or volume button to stop the tone mid way instead of letting it finish well I recently discovered that doesn't really work to well with my z1c... Lol anyone know if this is possible maybe it does work and I just didn't press it long enough or hard enough but I think I was pretty firm on the per button trying to make it shut up lol didn't work... Help me out
