Got a call from this number on 3-22-1016 @ 6:50pm CST. I didn't answer since it showed up on the caller ID as "Name Unavailable", of course I don't answer unknown calls anyways.
The 309 area code is from Illinois. As to the 056 not being a legitimate prefix I did a little research, but correct me if I'm wrong or my source is bad. Apparently 056 is a prefix that is starting to be used by ISP's as a prefix for VoiP calls. Only company I've been able to find so far for the 056 prefix is etisalat (www.etisalat.ae/).
