Received call on my office number.  Did not answer.  No message left.

Got a call on my office phone. He stated he was from my company and wanted to send me some material on retirement planning. He wanted my home address and my age. This didn't seem quite right because he should have already had that information.

Received a call to my work line.  When I answered, they hung up.

Got a call from it on my office phone... says he's from Smith Barney wanting to know if I'm interested in some retirement planning information.

who is this number?
