When you block a number on your Android phone, your phone won't ring when the person calls you, but the caller can still leave voicemails. The only way to prevent callers from leaving voicemails is to use an app that labels blocked numbers as spam. Your options depend on your phone
Because blocking the caller on the phone just automatically rejects the call, in which case it goes to your carrier's voicemail system. The only way to prevent that would be to block them at the carrier level. Contact your cellular carrier and see if they offer that service.
If contacting your carrier doesn’t solve the issue, you can try using a call blocker app. These apps can help you block specific numbers, and some can even prevent blocked calls from leaving voicemails on your device. Some popular call blocker apps for Android include Truecaller, Mr. Number, and Calls Blacklist
