A：Good morning!  

B：Can I speak to Miss Cooper please?  

A：Would you hold on a second, please? Miss Cooper's extension is engaged.  

B：Engaged. Oh, dear! Could you tell her it's a long-distance call?  

A：I'm sorry, sir. I can't interrupt her. I'm sure she won't be very long.  

B：How long do you think she'll be?  

A：I really can't say how long she'll be.  

B：Can I leave a message, please?  

A：Yes, certainly.  

B：Can you tell her I'm waiting to speak to her?  

A：Yes, sir. I'll ring her on an inside line if you like.  

B：Thank you very much.
