A method of operating a virtual private network includes the steps of: (a)
dialing a custom number; (b) receiving the custom number at a switch (20)
of a first carrier; (c) routing the call to a switch (18) of a second
carrier based on having received the custom number; and (d) when the call
to the switch (18) of the second carrier includes a plain old telephone
number translation of the customer number, routing the call over the
second carrier to a service switching point (26) of a third carrier.
