It appears as these people have changed their name again.  They are no longer calling themselves "Elite Information Solutions".  They are now going by the name "The Credit Voice".  They changed their name from "Elite Information Solutions" to "The Credit Voice" the day after Indiana Attorney General filed suit against "Elite Information Solutions dba Safeline Alert".  According to the Florida Department of Agriculture (licensing body of telemarketers in Florida) "The Credit Voice" is licensed to telemarket medical alert equipment at 495 Semoran Blvd. Casselberry, Florida. It looks like "The Credit Voice" main headquarters is located in Clearwater, Florida.
