<p>An apparatus and method are provided for locally intercepting and servicing a toll-free call, prior to incurring charges associated with routing of the toll-free call over a corresponding long-distance carrier channel. The apparatus includes a telephony-centric network server (408) and a central call management server (402). The telephony-centric network server (408) detects initiation of the toll-free call (602-606), it intercepts the toll-free call (610), and it services the toll-free call prior to accessing the corresponding toll-free carrier channel (612-616). The toll-free call is serviced according to a corresponding service procedure (404) stored within the telephony-centric network server (408). The central call management server (402) is coupled to the telephony-centric network server (408) over a data-centric network (406). The central call management server (402) maintains service procedures (404) and provides the corresponding service procedure to the telephony-centric network server (408) over the data-centric network (406).</p> |
