Hello ​@st34m, welcome to our Community! Not so nice that you are receiving spam calls, I totally understand. We can't do anything about this, sorry! This is because we cannot find out whether it is a spam number or normal number. We always recommend to just block them. If you'd rather not, because you're not sure if it's someone you want to reach, then it's best to just answer. If you know it's a spam number, you can hang up as soon as possible and block the number immediately. 

Sorry I don't have another answer for you. If you have any other questions, feel free to let me know!
