ABSTRACT:
A method and apparatus are provided for selectively routing a dialed telephone number. The apparatus intercepts a dialed telephone number having a plurality of digits and prevents the dialing of the number from being completed over the telephone access line. A comparator compares the digits of the dialed telephone number to a preselected combination of digits and also includes routing means for routing the dialed number along a first route if the compared digits are in agreement, but will route the dialed telephone number along a second route if the compared digits are not in agreement with the preselected combination.
