I also received calls from this number and confirmed with AIT customer support that it was them. I don't know why they would be calling their customers with an auto-dialer and then not picking up the phone and I don't care anymore. Doing business with AIT was an unpleasant experience and I have moved on to other providers and I am very glad I did. Any potential savings you may think you will get by using AIT are not worth it. Steer clear of this customer service nightmare.
