I thought of that too.

Recently, though, I get sometimes back-to-back calls (which I don't answer) with my name and number in the caller ID.

I don't know how they do that, but there's much I don't know about the current phone system, and much I don't like.

Block your own number? Only as a last resort.

I thought of that too.

I just this minute got a spam call from a breathless young lady named Angela. Angela was excitedly telling me that my warranty (product not specified!) was expired. Before I could expire also, from boredom and being annoyed, I just pressed my faithful BLOCK CALL button and poof! Angela disappeared. Yay!
