When one of my contacts calls, why doesn't my phone ring or vibrate?

[AC Question]

When one of my contacts calls, my phone does not ring or vibrate.

The caller gets and answer that I can't come to the phone and to leave a message, but phone does not ring or vibrate.
It just started yesterday.

Greetings and welcome to Android Central!

Just curious to know what phone do you have and wondering if call forwarding to voicemail was enabled somehow? Maybe try checking Accessibility > Answering/ending calls or something similar to that.

Hope you get it resolved.
