Who called from 4065305038

I don't know who they are, I didn't answer.
I've been blocking all 1-406 numbers.

Trying to "give away" a wireless home security system.  Didn't catch the name.

Got a call today from this number.  Screen ID said:  Security OT.  Didn't answer.  No message left.  I wonder if this is just another number for the same group that has called me and some others on this blog. The other number is from the same area code, but has a different screen ID.  Some people did say that this other number (406-931-3975, Political LP) was also trying to sell security or alarms systems.

Scam!  Watch the 406 area codes.  They don't respond to a "call back."  I registered with the DO NOT CALL.  I don't know if it will help.  Be careful out there . . .

Our home phone is on the DO NOT CALL registry, yet we received TWO calls this evening (we did not answer) from this number.

Caller-ID shows:

1) Security OT 406.530.5038
and
2) Laurel MT 406.530.5038
