Got a call from this number today. Some lady with a heavy, thick, foreign accent called and I could barely understand her. I could tell it was from a call center because I heard others talking in the background, probably from other cubicles. From what I did comprehend, she said something about illegal activity in my area. Funny, how could she know what illegal activity is going on in my area when she was calling from an out of area and out of state phone number? After I hung up on her, I found the 573-202-6263 number to be associated with ADT Security  based in Missouri, I personally doubt it's ADT with a call center in Timbuctu.

Just got a call from this number. Had let it go to Voice. Only got the end of a pre-recorded message. Couldn't tell what the purpose of the call was.

Telemarketers for GrantCo trying to sell mobile website services.

more calls to my business cell...I do not answer out of area calls.

Reverse white pages says this "company", VoIP,  is in Rolla, Missouri. My guess is that someone has hired a bunch of the international students from the UM at Rolla there to cold call random numbers.
