INTERNET PROTOCOL TRUNK GROUPS
First Claim
1. A method for routing an Internet Protocol (IP)-based call through a first IP-based network to a second IP-based network, the method comprising:
- receiving an IP-based call request in the first network;
identifying one or more IP trunk groups that can be used to route the call request out of the first network, wherein each of the one or more IP trunk groups represents a logical grouping of one or more IP interconnections between the first IP-based network and the second IP-based network;
selecting one of the one or more IP trunk groups; and
routing the received call request to an IP address associated with the selected IP trunk group.

Abstract
A system includes a core routing engine operable to receive a call setup request and identify one or more IP trunk groups through which the call setup request can be routed, select one of the one or more identified IP trunk groups and route the call setup request to an internal IP address associated with the selected IP trunk group. The system may further include an IP edge node associated with the internal IP address, the IP edge node in the backbone network and operable to receive the call setup request and route the call setup request to one of a plurality of IP addresses associated with a plurality of carrier edge nodes in the carrier network.

8. A method for configuring a Voice over Internet Protocol (VoIP) backbone network to route calls to an IP-based carrier network, the method comprising:
-
identifying one or more sets of IP interconnections between the VoIP backbone network and the IP-based carrier network that have common attributes; determining an IP interconnection type for each of the one or more identified sets of IP interconnections; and for each set of IP interconnections, defining an Internet Protocol (IP) trunk group wherein defining comprises associating the common attributes of each identified set of IP interconnections with a unique IP trunk group identifier.

9. A system for routing IP-based calls through a backbone network to a carrier network, the system comprising:
-
a core routing engine operable to receive a call setup request and identify one or more IP trunk groups through which the call setup request can be routed, based at least in part on a telephone number in the call setup request, the core routing engine further operable to select one of the one or more identified IP trunk groups and route the call setup request to an internal IP address associated with the selected IP trunk group; and an IP edge node associated with the internal IP address, the IP edge node in the backbone network and operable to receive the call setup request and route the call setup request to one of a plurality of IP addresses associated with a plurality of carrier edge nodes in the carrier network. - View Dependent Claims (10, 11, 12, 13, 14, 15)
