Where does the woman most likely work?

M: Hi, I’m with Spellman Technologies, and I’m calling to thank you and your company for the great job you did catering for our business luncheon last week.
W: Oh, don’t thank me. Your event was planned by my colleague, Nadia. I’m sure she’ll be happy to hear that you were pleased.
M: If Nadia’s in the office, I’d like to tell her myself.
W: Actually, she’s out today. But I can put you through to her voice mail so that you can leave her a message.
