Reported this number 406-478-2356 to the FTC, upon investigation it was found the number cannot be reported to the FTC do not call registry since it has been a non working number for more than 31 days in the State of MT.
The telephone company in MT stated this is a non working number, thus whomever is making these calls does so through some type of phone number emulation, hence the way the name of the city & state are written in the caller ID bar.
No known solution.
