Was getting at least 6 calls daily from this number, I've never answered them because I dont know anyone that lives in North Dakota, I blocked the number now I'm getting calls from 701-557-9150.
Best switchboard strategy when this number pops up on caller ID is to say nothing, then hit ANSWER and END CALL simultaneously. This has cut down tremendously on (701) 557-9XXX calls which are seriously scammi-whammi.
