Based on our tests in April of 2022, this still works. If you dial *67, then the recipient's full ten-digit phone number, your call will ring through. The recipient's caller ID will say 'Unknown Caller' or something similar. This probably isn't the best way to get the other person to answer these days, but you can tell by how the phone responds whether you've been blocked or not. If the feedback tone responds the same way as when you called from your number, the person is likely out of range of cellular service or having another issue. However, you've probably been blocked if it rings just like normal.
