I also got a call from the 8261 number, and figured it was the U calling for a donation to the annual pledge drive, but they never leave a message, and they have been very persistent.
Very odd. Starting to wonder if I have an outstanding balance at the Rhino Room!
I read in the Missoulian the other day that with Griz-Cat weekend upon us, both schools are competing to see how many new alumni they can get signed up before kickoff. I assume that is the source of the calls, a bunch of marketing students that are assigned phone duty one or two nights week.
I have been receiving calls from this and related numbers for 3 weeks (2/4/09-2/26/09). Other numbers: 406-541-8257, 406-541-8259, 406-541-8262, 406-541-8263, 406-541-8265. Seems to be about 2 a week, 6 calls total. They never leave a message, I've never answered, and once I was called at 6:39 a.m. This seems to be the most common number used. It could be connected to the U of M, since I graduated from there as well. I think they sold an alumni list to some credit card company. Don't think it's directly from UM though.
All UM numbers start with 243, so since they seem to come in with 541, I don't think it's a UM number. I've been getting calls to my cell phone from 541.8260 and 541.8255 for about a week now, as well as a weird text from a 702 area code.
