A method for establishing a call over a packet network may include receiving a call request via an originating trunk on a packet network from an originating call device. Status of an originating trunk and terminating segment may be determined. If the status of the originating trunk and terminating segment are within a first range, the call between the originating and terminating call device over the determined transmission path at a first data rate may be established. Otherwise, if the status of the originating trunk or terminating segment is within a second range, a determination as to whether the originating trunk and terminating segment can operate at a second, lower data rate may be made, and, if so, the call may be established over the transmission path between the originating call device and terminating call device at the second, lower data rate.
