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, from the first network, 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 number of the PDP and corresponding to an internal routing number of the first network;
responsive to the query, receiving the selected internal egress path identifier and a PDP telephone number from the PDP call resolution service; and
based on an identified source of the call, ignoring the PDP telephone number and routing the call through the first network to a destination endpoint of the second network, the destination endpoint associated with the destination telephone number via an egress path identified by the selected internal egress path identifier,wherein the PDP telephone number identifies a selected PDP destination endpoint and the method further comprises;
routing the call from the destination endpoint of the second network to the selected PDP destination endpoint using the PDP telephone number.

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, in a first network, a call directed to a destination endpoint in a second network, the call associated with a private dialing plan (PDP); requesting an internal egress path identifier; responsive to the requesting, receiving the internal egress path identifier and a PDP telephone number from a call resolution server, the internal egress path identifier associated with the destination endpoint and corresponding to an internal routing number of the first network; and based on an identified source of the call, ignoring the PDP telephone number and routing the call through the first network to the destination endpoint of the second network via an egress path identified by the internal egress path identifier, wherein the PDP telephone number identifies a selected PDP destination endpoint and the method further comprises; routing the call from the destination endpoint of the second network to the selected PDP destination endpoint using the PDP telephone number. - 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 a dialed number information service (DNIS) of the call, 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, wherein the egress path identifier identifies an egress path for routing the call to a destination endpoint associated with the destination number and the egress path identifier corresponds to an internal routing number of a first network, and wherein the PDP telephone number identifies a selected PDP destination endpoint in a second network; 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)
