Caller ID reads "Symphony Center" and the call comes daily.  They never leave a message.

On caller ID it reads "symphony center" and so far today they have called twice - I did not answer.  I did answer yesterday and asked them not to call.  About a month ago, they were calling a minimum of once a day.

Same here..

I think it is a number from the CSO (Chicago Symphony Orchestra)
They call all the time- no message but a pain.

Calls my cell # and never leaves message.

got a call from this number 3/5/2010  at 2:01 PM. No message.

My phone displayed a missed call from this number with no message left at 6:55 pm 1/29/10.

I've received several calls on my cell phone from this number, but I've yet to answer it. They usually call during business hours. They never leave messages. I googled the area code and it turns out the area code is in the Loop in Chicago.

called my phone, no message -- same thing happened with the same number ending in 3509. i only know 1 person with a chicago area code, though, so idk what it's about.

Called my cellphone and didn't leave a message. Right after that the same number except it was 3514 called and didn't leave a message. I thought it was my school, except there was no message.

THis is a scam. THey left a message on my c# and informed me of a new Navigator I was going to win. I called them back and asked who they called at my number. They hung up. I P$##ed about not having a new Navigator.
