Abstract
Aspects of this disclosure are directed to a method of routing toll-free telephone calls using a toll-free exchange, thereby minimizing the number of hand-offs, increasing the technological capability and reducing the ultimate cost of the toll-free call. Toll-free subscribers are generally assessed a cost based on each exchange plus the duration of the call. Subscribers are also limited to the decades old technological standards of PSTN switching. It is therefore an object of the present disclosure to minimize the number of exchanges, promote technological possibility and simplify the process of directing a toll-free telephone call by providing a toll-free exchange.
Claims20
A method for routing toll-free calls through a toll-free exchange, the method, performed by a policy router of the toll-free exchange, comprising:
- receiving, from an originating responsible organization (RESPORG), a toll-free call, wherein the toll-free call is directed to a toll-free subscriber that is served by a terminating RESPORG;
- querying a database to determine a RESPORG identification associated with the terminating RESPORG, wherein the database is associated with the toll-free exchange and stores the RESPORG identification associated with the terminating RESPORG;
- and
- routing, to the terminating RESPORG, the toll-free call based in part on the RESPORG identification.
A method for routing toll-free calls without using a carrier identification code (CIC), comprising:
- receiving, from an originating responsible organization (RESPORG), a toll-free call, wherein the toll-free call is directed to a toll-free subscriber that is served by a terminating RESPORG;
- querying a database to determine a RESPORG identification associated with the terminating RESPORG, wherein the database is associated with the toll-free exchange and stores the RESPORG identification associated with the terminating RESPORG;
- and
- routing, to the terminating RESPORG, the toll-free call through a protected network based in part on the RESPORG identification.
A system for routing a toll-free call using a toll-free exchange, the system comprising:
- at least one session border controller for routing a data portion of the toll-free call within the toll-free exchange;
- a policy router for determining, based at least on data included within the data portion, a responsible organization (RESPORG) identification (ID) associated with a terminating RESPORG;
- a service control point for storing the RESPORG ID of the terminating RESPORG;
- a database for storing enrollment information associated with the terminating RESPORG;
- and
- a media gateway server farm having one or more server computing devices for routing a media portion of the toll-free call based in part on the RESPORG ID of the terminating RESPORG.
