I've never listened to the music long enough to get a human, but now that I read these, I realize it must be for MSDN revewal, which expires at the end of this month.
Got a call from the same number-- also music for a few seconds, then the call disconnected. I don't have an MSDN subscription, only TechNet (which doesn't expire til next spring). WTH?
Funny... I didn't answer, so the call was redirected to my voice mail. I got a massage which consisted of 20 seconds of music, followed by an agent saying "hello?" and hanging up. This predictive dialer clearly sucks.
Like other posters, I do have an MSDN subscription and already renewed it a little while ago. Call centers call their lead lists based on the info they were provided by their client (Microsoft in this case). Their database is not directly connected to MS and is not refreshed in real time (if at all). It is understandable that the call center may not be aware that my subscription was renewed.... but still, their dialer sucks...
