When people are talking on the phone, "this" relates to the person/section speaking, and "that" to the person/section being spoken to.claude23 said:Good afternoon,
On the phone, I heard people saying who's that instead of who's this ? May I use both ? If not , why ?

The person answering the phone is a business might say:
"This is the Inland Revenue Compliments Section, how may I help you."
Similarly, a person might ask:
"Is that the Lost Property Office?"
"Is that Miss Prim, PA to the CEO?"
When the phone call is finished, someone could ask "Who was that on the phone?"
"Oh, that was Donald Trump again. He's still begging me to work for him."
If you say "Who's this?" on the phone, you're asking "Who am I?"
Occasionally people say "Do you know who this is?" meaning, "Do you know who I am?" "Do you recognise my voice?"
