Shameless plug: for mobile devices, consider YouMail. If the ANI are already known, the free version should do a decent job of blocking them. For spoofed/one-and-done campaigns, the better option is the paid version with the captcha for non-contacts.

I have been receiving the "tax resolution center" / "loan determination" / "debt consolidation" scam calls, many of them from TFNs, for close to a year at this point. They often overwhelm my phone, sometimes several come in at the same time from different DIDs, and they often interrupt other tasks or calls.
I don't know what to do about it other than change my number (TMO), which I'm unwilling to do with how much 2FA and business stuff is tied to it. Turning on the iOS "ignore calls from unfamiliar numbers" is also totally not an option because I get lots of legitimate calls from unfamiliar numbers. It's really, really, really bad. I seem to have been singled out for an exceptional volume of these.
I have on occasion pressed '2' on their IVR to speak to an "agent". The transfers are instant with no hold time. 100% of "agents" have been Indian.
