this number called me and I know its some kind of crank call as I have now been getting many of them every morning and every night from all different types of phone numbers.  When I search on the Internet it appears the company is an Alaskian Government phone number which when I call, I actually get someone's voice mail.  It appears that someone is able to use other phone number such as this one to place outgoing phone calls to test to see if my number is a valid anserable ' selllable' phone number.

Everytime I get a call from 907 or 866 I just unplug my phone and let it ring ring ring without my hearing it.  This is still a nusance.
