My sister's house is on a party line system that uses some kind of frequency selector to select which house is rung on the main phone. When she tried to put in an answering machine it answered for everyone on her line. In the letter the phone company sent her telling her to disconnect they said she could by extra frequency selectors for $50. Is there any other sources for these? Can one be built easily? Is there an ID on hers that tells what frequency it is?
