Call on a business line from some Indian-sounding person on a over-compressed VoIP connection looking to send a "Free" diabetic meter. Do not give them any real information, only false information. This is very likely a medical insurance fraud scam.
Seen these "free diabetic meter" before with a completely automatic/robotic/voice-response lead generation system that was really creepy. Possibly it didn't scam enough people, so they are now using cheap over-seas call centers.
