Sometimes I am in a situation where one person(person A) needs another(person B), who(B) is working close to me but doesn't hear the first person(A) and then the first person(A) shouts to me to inform B to go near to them. The scenario is:
A: Hey B come here.
A to me: Tell him(B) to come here
I am confused what should I say to B. If I translate from my native language, then I would say, "Hey B, A is calling you". But, I think this is not correct in English. May be Hey, A is looking for you or A needs you is more appropriate, but this doesn't signify that A is actually shouting/saying to B to go there. May be a better phrasing would be Hey B, A is asking you to go to him.
What is usual sentence to be used here in English and specifically in Australian English?
