The number leads back to something called predicto.com. I called both predicto and heycosmo and told them they contacted an secure internal government mobile phone and they were kind of scared when i threatened legal action.
Received unsolicited call on my cell phone, which is listed on the Do Not Call registry. Call rang for only one ring and then was disconnected before I could answer it.
Received call at 4:53 EST. Rang a for a second then disco'd, no message left. I won't call them, as I won't risk it forwarding to one of those Carribean "per-minute" phone scams.
