I get about 3 calls a day from this number, all hours. It does not have a caller id, nor does it say anonymous or unknown. Once it had V81812360700015 for the id. I have answered this call a number of times as it is a local number for me. No one answers and after a minute it hangs up and the phone starts beeping fast. I am also getting calls from a 972-370-3053 with the same issue. I suspect they are related. I suspect this is a scam for a security system or medical alerts as I have gotten a lot of calls around those lately.
3/27/15 Well these jerks have started up again. We received 4 calls from them in 2/15, one on 3/11/15 and the one today - no msg left on ans. machine as usual. When we are home we press " talk" then immediately "Off" to deal with unknown callers. For some reason the number of robo/telemaketer calls has declined considerably in March but will no doubt increase with the elections - heaven help us please.
