Abstract

A communication network, which includes a plurality of switches, routes a call from a receiving switch to a destination switch either directly or through an alternate switch. Either the receiving switch or the destination switch, or both, analyze the contents of a store to determine whether the calling party or the called party is marked for alternate routing. The call may be routed to the alternate switch either from the receiving switch or the destination switch if the call is marked for alternate routing. The inventive method includes transmitting a two part call information signal to the destination switch from the receiving switch if the call is not marked for alternate routing. If the call is marked for alternate routing, a three part call information signal is transmitted to the alternate switch. The alternate switch then recreates a two part call information signal and transmits that signal to the destination switch as it routes the call thereto.
