I got a call from this number just after midnight back on August 15th. Then I got 2 calls back to back last night (9-21-12) right at midnight. My caller id showed Washington.
I got a call at 11:17 pm from this number July 4,2012. No message left, but at about 2am I sent a text message and got no response. I called the number back a few minutes ago and a recorded message came on from a company called lucky talk. Somebody must have pranked me by giving them my number because they sound like a chat line.
My guess is that it is tied to a mobile phone app. Download an app and start getting these calls. I just got these calls today at 747 pm. Never heard of it but I downloaded a phone app for movie showtimes just a few hours earlier.
