A system and method for routing a call over a packet network. A call request may be received from a calling party to call a called party at a network address. At least one potential call path over a packet network may be determined to connect the calling party to the called party at the network address. Network performance information associated with each potential call path may be accessed and a determination may be made that each of the call paths are impaired or congested. In response to determining that each of the call paths are impaired or congested, the call may be routed over a call path other than one of the at least one potential call paths to enable the calling party to communicate with the called party.
