Lucky you. I've been letting calls from any number I don't recognize go to voicemail for years and nothing ever seems to change.
Setup a whitelist, I think it's native on iPhone and there are multiple Android apps. Only calls from your contact list will ring through. My voicemail is, "You're getting this because you're not on my contact list, send a text and I'll get back to you."
