Shibu,
perhaps you would get more replies if you used a proper Subject.
Remember most don't read something like "Digest 920".

As for your problem, i don't know what SLIC means, but i know there are  
working circuits out there to detect ring and off hook, which can be built  
with discrete components and connected to IO pins of your Atmel. Google  
for "phone in use schematic" .
You will then find plenty of stuff like this:
