- Good afternoon. May I speak to Tom, please?
- Sorry, Tom is out at the moment. And who is speaking?

- Alex, Tom will be back in an hour. Do you want to leave a message for him?
Please, tell him to call me back when he is free.
- Of course, Alex. Anything else?
- No, thank you. Goodbye.
- Goodbye.
