I too am in Flagstaff and just received a call from this number at 8:01 pm 2/6/08. Call ID indicated private call. I answered but caller hung up without speaking. UGH!!!
you will have to answer it and stay on the line each time until someone answers and let them know that you are or are not interested and they will stop calling.
I got 6 calls from this number since last night. There were no messages and when I finally picked up, they hung up. I called back and the machine said that the extension was unavailable.
I also started getting calls from the 201-918-3048 yesterday about 9 of them then the calls started coming in from 908603-0385 5 yesterday and 3 so far this morning. I had started to sign up for information for google money tree but decided not to submit my info. Somehow they captured the phone number anyway.
