Vtech CS6859 Manuals

Call forwarding is NOT a function or feature of the VTech 6041
cordless phones.

It is offered by some telephone service providers, but their
procedures are proprietary and specific to that individual
telephone (service) company -- if they offer it at all.

Good luck!

Contact the phone company in India and ask them the question.

I went online and downloaded the manual for this produst and followed all the trouble shooting procedures until one of them was successful. I didn't download the entire manual but selected various pages listed in the index and printed what I needed. Accessing the appropriate manual was an easy process because of the manner in which they were identified on the vtech website.
