Patent number: 8401161Abstract: 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.Type: GrantFiled: May 9, 2007Date of Patent: March 19, 2013Assignee: Level 3 Communications, LLCInventors: Richard Terpstra, Greg Gualtieri, Dan Jordan, Janis Griffin, Murli S Nair, Susmita G Saha

Patent number: 7657017Abstract: A method includes jurisdictionalizing a long distance intra-MTA call as a local call. The method may further include receiving an intra-Major Trading Area (MTA) call, determining whether the intra-MTA call satisfies terms of use of a direct connection to a terminating network, and routing the intra-Major Trading Area (MTA) call directly to the terminating network via the direct connection if the intra-MTA call satisfies the terms of use of the direct connection. A method for routing calls includes determining that a received intrastate call is an intra-MTA call, determining whether the intra-MTA call satisfies terms of use of a direct connection bypassing a Local Exchange Carrier, and routing the intra-MTA call for termination via the direct connection if the intra-MTA call satisfies terms of use of the direct connection. A system includes a switch configured to jurisdictionalize a long-distance intra-MTA call as a local call, and may be further configured to route the call over a local route.Type: GrantFiled: May 5, 2008Date of Patent: February 2, 2010Assignee: Level 3 Communications, LLCInventors: Bill Long, Richard Terpstra, Greg Gualtieri, Dan Jordan
