Where does the woman work?

M Thank you for calling Softly Spoken. How may I direct your call?
W My name is Katherine Williams, I work over at International Finance and I am hosting a meeting with some of our Japanese clients next week. I’d like to speak with Mr. Mashimoto about doing some interpreting for me at the meeting so that I can communicate more easily with everyone. I heard he’s really good.
M I’m sorry, but Mr. Mashimoto is out of the office today. But I can give you his cell phone number so you can reach him.
W Thank you. I really need to speak with him.
