I wouldn't answer the phone unprofessionally- especially if I was addressing an important person
Actually, many people struggle with answering the phone because they don't know what to say.
I would suggest that you answer the phone in a formal way.
Here's the main dialogue:
Caller: Hello?
You: Hello
Caller: May I please speak to ----?
You: (if it is you) speaking, who is calling please?
(if it isn't you) who is calling please?
Caller: ---- from ----
You: (if it isn't you) sorry, s/he'll be just a moment or s/he's out can you call
back later or s/he's out, would you like me to take a message
Caller: ok.... or no thanks, I'll call back later

It would depend on the size of the telephone box, but probably not.
That depends on how large your telephone box is.
