Who called from 4128023100

I got this call at 5:33PM also but on Wednesday. I dont know whot this is and they dont leave messages either.

Received a call from 412-802-3100. Lady asked for someone by name. Told them they had a wrong number. Lady very polite, apologized and said she would not call again.

This is the UPMC reminder line for appts. It is a general number and is automated. I received a msg reminding me about my son's appt next week.

This is also used for a place called Nationwide Credit Inc.  Collections agency.

412-802-9260

I got a message on my phone at work from this number (08/30/2012).  I do have business dealings with staff at UPMC, so I suppose this is probably how I got this message.  It just played music, the kind you get when you're on hold on the phone.  It just played for about 2 minutes and then went to an "off the hook" beeping.
