one of our client purchase login id and password from a company for making international call through this portal.the party charged Fixed charge of Rs .36000+calling charges  and on net total amount they charge service tax (as that company registered in service tax as telecommunication service head.)

i am confused whether the tds is applicable under the head contractor i.e 194c or under section 194j
