- dymk 4y agoTo reiterate the problem: Legitimate callers don't all use VoIP. I don't have every legitimate caller's phone number in my contact list. Blocking all numbers not in one's contacts list is therefore not a solution to blocking spam calls while allowing legitimate callers.
- thfuran 4y agoYes, but many legitimate callers are voip so blocking all voip calls also isn't a good solution if you're looking to avoid blocking legitimate callers.
