Hello,
I get a lot of spam/robocalls (usually around 5 per day) and I recently signed up for verizon's "Call Filter" app which seems to block most of them, however it looks like the ones that still get through are VoIP calls that show a name or business unlike most of the blocked calls which show "UNKNOWN NAME". It could be that these particular calls are legitimate numbers being spoofed by scammers. It would be nice if there was a option for this app to block all VoIP calls, is this a possibility?
