How can I get Income Tax benefit from HRA?

Presently I am outside India for the last 10 months.My parents live in Kolkata.I work in a chennai based MNC, but I have no accomodation there.In such case,is it possible to get house rent slips from my Father and submit them as HRA in order to obtain the tax benefit.How is it possible or is it possible at all?

Thanks in advance
