Does the phone have a dial tone? If so, go to
and go to Advanced Call Forwarding and make sure your home phone is checked and no other call forwarding option is selected.
If it doesn't have a dial tone, then the problem is more localized and you should inspect the connections to your modem and your phone devices.
