From the US? Its a pain getting anything done with IC within India, AT THEIR OFFICE, for that matter! Sorry to be so negative, but unless you're lucky to have a really knowledgeable and helpful person take your call, you're going to be left spinning in circles...

Having said that, there are quite a few on this forum that might be able to give you specific direction. I for one can't, because I stay away from AI/IC as far as possible.
