Abstract
A system and method that establishes a phone call over a packet network. The process may include receiving a call request from an originating call device on a packet network to call a terminating call device. A first transmission path may be determined between the originating and terminating call devices. Status of a terminating segment at a first terminating trunk may be determined and, if the status of the terminating segment at the first terminating trunk is within a first range, a call between the originating and terminating call device may be established via the first terminating call trunk. Otherwise, if the status of the terminating segment at the first terminating trunk is within a second range, a second transmission path via a second terminating trunk between the originating and terminating call devices may be made.
