  • storing an expected network topology of a first network of said network access server;

    detecting whether a current network topology deviates from said expected network topology;

    detecting whether said current network topology continues to deviate from said expected topology;

    identifying a portion of said first network that deviates from said expected network topology;

    reporting a detected continue deviation of said current network topology from said expected network topology to a network operator; and

    routing calls away from said portion of said first network.
