How can I avoid foreclosure?? Any suggestions??

I am about to start the foreclosure process. I know the lenders will send mail, but is there a way to get them to stop calling my home and buisness? I heard that you can send a letter to the lender and they have to quit calling and can only contact you through the mail.

i can become current, with mortgage and late fees in month three. will that end the foreclosure and prevent me from losing the house?
