Why "to call that person direct" is used? I thought "directly" was right.

That's a very good question, Irina!

The word 'direct' can also be used as an adverb (i.e. without the -ly), but I'm afraid I can't give you a rule for when you can use 'direct' instead of 'directly' as an adverb. Maybe one of the others can do this.

One piece of advice I can give you, it might be best to learn this group of words - 'call someone direct' - as an idiom. It means to phone someone without a "middleman", such as a switchboard operator or secretary.

If I said "call someone directly", I would probably understand the meaning of 'directly' to be the same as 'right away' or 'without delay'.
