CID showed Dir Asst TX. I don't answer calls like this. No message was left, so I have no idea what the caller wanted. Not that it matters because I figure it's a scam or telemarketing call anyway.
I often pick up, but don't speak. Robo calls will then hang up. But a real person will usually say something. This one hung up. Who wants to answer "directory assistance " anyway. Another site says they're selling home security, I think.
