From reading and researching the comments here are accurate. It was a Katherine Bell she states that your resume somehow appeared on her desk.
When she leaves the message she doesn't identify the company nor the position. Upon calling back it goes directly to voice mail as others have indicated.
If you have been applying for jobs it's possible that your resume is public on the sites you have used. That is probably how she obtained your contact information.
If you didn't apply to her company be leery. Jobs worth having don't contact you out of the blue.
I did return the call and will obtain any information given me providing she calls back. If this isn't updated you can assume she didn't.
