Abstract:
A method for routing a toll-free call through a network includes receiving a toll-free call from a call origination endpoint, determining an identifier associated with the call origination endpoint, determining a meet point trunk based on at least a portion of the identifier if a DAL is not available, and routing the toll-free call to a LEC via the determined meet point trunk. A system for routing a toll-free call entering a network to an appropriate carrier includes an inbound gateway device configured to receive a toll-free call from a call origination endpoint having an assigned telephone number and to query a core routing engine (CRE) for a route plan using the assigned telephone number, and a CRE configured to select an interconnection access line based on the origination endpoint telephone number, wherein the interconnection access line is connected to a LEC that is operable to route the call to the appropriate carrier.
