SYSTEM AND METHOD FOR ROUTING CALLS ASSOCIATED WITH PRIVATE DIALING PLANS
First Claim
1. A computer-implemented method for establishing a call from a first network to a second network, wherein the call is directed to a destination telephone number associated with a private dialing plan (PDP), the method comprising:
- querying a PDP call resolution service operable to select an internal egress path identifier from a plurality of internal egress path identifiers, the selected internal egress path identifier associated with the destination telephone numbers of the PDP;
responsive to the query, receiving the selected internal egress path identifier from the PDP call resolution service; and
routing the call to a destination endpoint associated with the destination telephone number via a egress path identified by the selected internal egress path identifier.

Abstract
Methods and systems for routing a call including a destination number associated with a PDP including a routing engine operable to route the call to a PDP call resolution server, and a first switch operable to receive an egress path identifier and a PDP telephone number from the PDP call resolution server, the egress path identifier identifying an egress path for routing the call to a destination endpoint associated with the destination number, and the PDP telephone number identifying a selected PDP destination endpoint and a second switch operable to receive the call based on the egress path identifier and route the call to the selected PDP destination endpoint using the PDP telephone number.

7. A computer-implemented method for establishing a call associated with a private dialing plan, the method comprising:
-
receiving a call directed to a destination endpoint associated with a private dialing plan (PDP); requesting an internal egress path identifier; responsive to the requesting, receiving the internal egress path identifier from a call resolution server associated with the destination endpoint; and routing the call to an egress path identified by the internal egress path identifier. - View Dependent Claims (8, 9)

10. A system for routing a call including a destination number associated with a private dialing plan (PDP) where the routing is otherwise unknown and not available from the DNIS, the system comprising:
-
a routing engine operable to route the call to a PDP call resolution server; a first switch, in communication with the PDP call resolution server, operable to receive an egress path identifier and a PDP telephone number from the PDP call resolution server in communication with a private dialing plan information server, the egress path identifier identifying an egress path for routing the call to a destination endpoint associated with the destination number, and the PDP telephone number identifying a selected PDP destination endpoint; and a second switch operable to receive the call based on the egress path identifier and route the call to the selected PDP destination endpoint using the PDP telephone number. - View Dependent Claims (11, 12)
