An apocryphal moment on the phone

Except this happened for real, when the phone rang in the middle of our weekly morning meeting:

Me: Good morning, (name of company), how can I help?
Unknown caller: I'd like information on a particular commercial property.
Me: We're in a meeting at the moment, but I'll get our property manager to give you a call back in half an hour.
(before I can ask for any information from her)
UC: Do you want my phone number?
Me: Nooo... I'll just try and guess it, shall I?

Well, I didnt say that, but oooh the temptation!
