By accident I discovered a way to use the phone for in-house calls:
Dial your own number and hang up immediately after the last digit. All
phones in the house will ring and (hopefully) the person you wanted to
talk will pick it up. Is this a special "feature" of our exchange (we
are part of tiny Granby Telephone Company in Western Mass.) or does
that work everywhere?
