ABSTRACT:
Embodiments of the invention include a method for routing an Internet Protocol (IP)-based call through a first IP-based network to a second IP-based network. The method includes receiving an IP-based call request in the first network; identifying one or more geographic trunk groups that can be used to route the call request out of the first network, wherein each of the one or more geographic trunk groups represents a logical grouping of one or more IP trunk groups between the first IP-based network and the second IP-based network; selecting one of the one or more geographic trunk groups; and routing the received call request via the selected geographic trunk group to an IP address associated with the selected geographic trunk group. Other embodiments are also disclosed.
