1. A method for routing a call, said method comprising:

  • receiving from a first network a call request from a calling party to call a called party at a network address of a second network;

    determining a potential call path to connect the calling party from the first network to the called party at the network address of the second network;

    determining, using performance information packets (“

    PIP packets”

    ) generated by network nodes along the potential call path, that the potential call path is impaired;

    accessing network performance information associated with a plurality of potential call paths, the network performance information gathered from PIP packets generated by network nodes along each of the plurality of potential call paths;

    determining a condition of each of the call paths within the plurality of potential call paths based on network performance information associated with each of the call paths;

    comparing the condition of each of the call paths within the plurality of potential call paths based on the network performance information associated with each of the call paths; and

    routing the call over a second call path other than the potential call path to enable the calling party to communicate with the called party at the network address of the second network, wherein the condition of the second call path is determined to be better than that of the potential call path.
