Read the below conversation.

W: Good afternoon! Dr. Perkins' office.

M: Good afternoon. I'd like to speak to the doctor. Is he in?

W: Who is that calling, please?

M: My name is Li Hong. I'm from China.

W: I'm sorry. Dr. Perkins is now at an important meeting and can't answer your call.

M: I'm an exchange scholar. Dr. Perkins asked me to give a lecture. There are some details I want to discuss with him.

W: I see, but you must speak to himself about that. Oh, well, if you leave your number, I'll tell him to ring you as soon as he is available.

What would the listener say?


M: Thanks. My number is 7838298.
