My GF got several hang-up calls from this number. What they did not know is I work for one of the Regional Bell Telephone companies. This number is registered to an automobile leasing and finance company. They also appear to provide 3rd party extended warranty coverage for new cars. Further delving indicates the owners are located in CA but are established in India. My suggestion is to call your local Regional Telephone provider (Pacific Bell, Bell South, Verizon etc..) and register a complaint. I would also contact the FCC "Do Not Call" Registry at follow website and follow the instructions to have them fined for a monetary forfeiture: http://www.fcc.gov/cgb/consumerfacts/tcpa.html If they get enough $1000-per-call fines from the FCC this will stop their telephone games very quickly.
