Good trick, once

Lately we’ve received a number of telephone answering machine recordings that say, “Hello? Hello? … Hello?” Then a hangup. It sounded as if we had called _her_ when this person had called us. We wondered if it was a wrong number, or some weird network switch confusion.
Well Occam’s razor needs application: It’s a new telemarketing technique to get past call screening. Okay, they got us once, but we’ll never pick up on that one again. Bye bye.
