Hello.
Is this Mr. Green's office?
Yes, it is.
Is he there?
I'm sorry, he isn't. He's at a meeting this morning.
What time will he be back?
He'll be back after two o'clock but he'll only be in the office for an hour.
Can I reach him in the conference room?
I'm sorry, but they aren't taking any calls. Can I take message for you?
This is Anne Lucas in the accounts office. I would like a word with him, please.
I can ask him to call you after the meeting. Can I have your number?
Yes, it's 488-6361. He can reach me there until three o'clock.
