Who called from 3123344556

I got two calls last night from 312-334-4556. Called the number this morning. It said it's Brooks Institute of Photography. I did previously contact them for information, so that's why they've called. I wish they identify themselves on Caller ID properly.

This number called me on my cell phone    Did federal law approve marketing calls on cell phones?

I got a call from this number today.

this number called june 27 and did not leave a message

The number is a call center for various educational institutions around the country--it's usually a follow-up call and is very harmless
