VM cannot block calls at source. How would they know what they are? The scammers also spoof numbers and change them regularly to get round any call blocking lists.
Tps is not always successful but it definitely helps to stop calls from reputable organisations who obey the rules but who may otherwise call you from lists they have got from elsewhere.. The scammers just ignore it because they know they can't be traced.
