Think I should listen to it?

I had a missed call on my cell a couple days ago and the number was my cell number.  Now I’ve seen caller ID numbers masked on land lines and I’m sure there’s the same capability with cells, but since when did telemarketers get access to cell numbers and bother to a leave message? 

And yes I’ve watched Primer at least half-dozen times.

It’s most likely a Cingular thing, AT&T or whoever the hell they are now.
