Who called from 5132880075

I believe it's a voice mail number of Cingular.

I would like to know who and how I received a call from this phone number. also why I got this call.

call the number and ask who they are.

The caller left no message, although it looked like there was a voice mail from that number.

I had a voice mail from that number. My phone did not ring, but I got a notification alert.  The voicemail was from my doctor's office reminding me of an appointment. This must be some kind of service that delivers voice messages.
