This might be a dumb question, but an old friend recently called and left me a message on my cell phone. The message asked me to call back him back when I had the opportunity. Of course, he calls from a restricted line and forgets to leave me his phone number.

Is there any way I can find this person's number? I probably know the answer to this, but I just wanted to see if there was something I could do. Would the number appear as "restricted" on the cell phone bill?
