[speaker001:] Hello, Can I speak to Tom, please?
[speaker002:] I'm afraid he is not in at the moment.
[speaker001:] May I ask what time he will come back?
[speaker002:] I think he will come back at 3 p. m. Do you want to call later? Or would you like to leave a message for him?
[speaker001:] I'd like to leave a message. Please ask him to call me back as soon as he returns. I'm A and he has my number.
[speaker002:] OK. I will do that.
[speaker001:] Thank you very much. Bye.
[speaker002:] You're welcome. Bye.
