They call, answering machine picks up, plays my message, caller hangs up. Caller ID just says OUT OF AREA, even thought the area code is a local area code. I have call screening. I will never answer these calls. I just turn off all the ringers and if I happen to notice a call coming in, and I don't recognize the number, I just ignore these calls. If I do recognize the number, I pick up. People either reach me that way, by fluke, or they leave a message and I return the call. End of story.
(213) 358-4135 and...358-4128, - 4108, - 4114, - 4119 all numbers used by the same robo-pest. As soon as I see (213) 358-4xxx, on the cid, I just ignore it. Anyway, they do not leave messages, they just want us to listen to their recording. Let them run down to the sewer.
