It depends upon what is meant by "long distance".  Cancelling your
inter-lata toll carrier subscription, as Pat tells us, doesn't
prevent your modem from calling 10xxx.  It also doesn't prevent
intra-lata toll calls, which are carried by your local telco,
regardless of your inter-lata carrier.

In some areas, your local telco can offer a class-of-service that
prevents any calls beyond your local calling area, regardless of
which carrier would otherwise handle them.  If this service is
available, it's probably the best answer.  If it isn't, a
toll-diverter can be used, but you have to update its memory
whenever a new prefix is added in your local calling area.
