How do I block voicemails? I have call block, but they are still able to leave a VM?

[Windows Central Question]

I have call block, but they are still able to leave a VM. Is there a way to disable these blocked numbers from leaving a VM?

This is possible, but you'll have to ask your carrier to block those numbers for you on their network. If you block them on your phone they will only get redirected to your voicemail, so the call passes through your carrier, but stops when it reaches your phone. But if your carrier blocks their number on their end, then the caller won't be able to call your number, they will just hear busy tone.
