I would like to have a device to prevent outgoing long distance calls
from my system. This will prevent abuse when rates are high. What I
want is a box which will go between the modem and phone line, and
monitor the outgoing tones. If the first tone is not a "1", the call is
allowed, otherwise the line is disconnected.

This sounds like an obvious item to have available, but I haven't seen
it advertized, and the local phone stores don't seem to have it. Can
anyone recommend such a device, or should I just build my own?
