Service tax input credit


(Guest)

A Co & B Co are sister concerns.

B's telephone bills are paid by A.

Telephone connection is in the name of B Co and the payment is made by A Co.

By this A's name appears in the bill.

Who is eligible for the claiming of input credit?

I refered in one of the site wher it says" service tax credit in  respect of telephone connection can be availed only if such telephone connection is instyalled in the premises where output service is provided"

Is this condition enough for claiming credit.?
