Been experiencing robocalls too. I use Hiya, but it's not a complete solution. Now I just let every call I don't recognize go to voicemail unless they call twice. It really sucks for the elderly, the sick, and the otherwise vulnerable because they're more desperate to hear from a doctor or caretaker or somebody without saved contact information / less technically savvy or on a landline / otherwise more likely to fall to these scams.

I'm wondering, is VoIP easier to call block than general call service? If it is, the inability or unwillingness by the telecoms to address this issue might prove to be a systemic disadvantage (though I'm pretty sure they make most of their margin nowadays from selling cellular data).
