Just spotted a post by Tomi Engdahl with some links to circuits that interface the 8051 to the telephone for home control.

You might be very interested in the section "Remote controlling using telephone" in this link.

If those more experienced than me with this type of circuit don't jump into this thread, you probably will find all the help you need in any of the 8051 micro forums.
