Got a call from this # 5/18/2013, 1:44p no message, ID shows 4582010467. First time for this one. Wish I could program the "call block" response my Panasonic phone gives. It just sends a "busy" signal, then hangs up. Would like to have it send the universal phone company message for an invalid or out of service number, 3 tones, and "this number is no longer in service, hang up and try your call again. We have all got that at some time, just record and play it back when you pick up the line. I suspect that the telemarketers systems would recognize that and delete that number from their list, ------ or, maby not ??
