1. A method, comprising:

  • at a session border controller (SBC);

    modifying a route for media of a media session when an alarm-state of an alarm condition is changed from unsatisfied to satisfied, the route being within a Session over Internet Protocol (SoIP) network and including at least a source endpoint, the session controller, an original intermediate destination endpoint selected from a plurality of intermediate destination endpoints, and a destination terminal adapter, an indicator of the alarm condition received from an alarm manager of an SBC network controller and based on session data about the media session stored within a session detail record (SDR);

    wherein modifying the route for media of a media session includes the SBC generating the SDR which contains the session data about the media session, the session data including session layer parameters and extrinsic parameters, wherein the session layer parameters include at least one of a call duration indicator, a start time indicator, an end time indicator, a source endpoint indicator, a destination endpoint indicator, a delay indicator, a media quality indicator, a packet loss indicator, a packet delay variance indicator, a quality of service parameter, and a ratings factor (r-factor),wherein the extrinsic parameters include at least one of a time-of-day indicator, a day-of-week indicator, a number-of-calls indicator, and a route cost indicator parameter,the SBC sending the SDR to the alarm manager of the SBC network controller, andthe SBC selecting a different intermediate destination endpoint from the plurality of intermediate destination endpoints with which to route the media session, such that the modified route bypasses the original intermediate destination endpoint in reaching the destination terminal adapter.
