Ha, ha. I don't like it when I get these phone calls from "private" or long distance phone numbers. Mostly I Google them to find out where the number is coming from. In most cases, I just assume that it's someone trying to sell me something or someone who dailed the wrong number and don't bother answering. If the caller doesn't leave a message, then the call was not that urgent, IMO. That's an interesting and useful app. Thanks.
