Who is Mr. Lewis talking to?

W: Hello, Mr. Lewis.(59)This is Ashley Mason from Top Travel.(60)I’m calling to see if you’re still interested in the special deal we offered you on the Summer package. The deal is good for only one more day. If you buy it at this time, we will pay your travel insurance for you.
M: Thanks for calling Ms. Mason. I’m still very interested in the package. I think it’s a great deal. I’m sorry, but I can’t talk now because I’m in a meeting.(61) Can you please call me back in half an hour?
W: Can I call you back in an hour? I’ll be away from my desk until then.
M: Well, I have another important meeting. Maybe I will call you later today.
