Allo?

Gus has been chatting up a storm on Jonathan's calculator the past few days. Who is he talking to? Ana, the cleaning lady. He walks around with the calculator to his ear, saying "Allo? Cleaning lady? Allo, cleaning lady." Is he tying to tell us something about our housekeeping skills? Is he calling her because she is so pretty (she is very attractive)? I wish he would continue his conversation so I could eavesdrop.
