1. A method comprising the steps of:

  • receiving, by a message processing gateway, alarm event data indicating that an alarm system has detected an alarm event;

    evaluating, by the message processing gateway, whether the alarm system is registered among a known group of alarm systems serviced by the message processing gateway; and

    if the alarm system is deemed registered among the known group of alarm systems serviced by the message processing gateway, then causing, by the message processing gateway, establishment of a two-way voice channel between the alarm system and a central alarm monitoring station over a packet-based network and transmission of the alarm event data to the central alarm monitoring station over the packet-based network,wherein establishment of the two-way voice channel between the alarm system and the central alarm monitoring station over the packet-based network comprises;

    opening a voice channel between a telecommunications switch and the central alarm monitoring station;

    determining whether the voice channel between the telecommunications switch and the central alarm monitoring station remains open after transmission of the alarm event data to the central alarm monitoring station by monitoring for a disconnection after the central monitoring station acknowledges receipt of the alarm event data; and

    in response to determining that the voice channel between the telecommunications switch and the central alarm monitoring station remains open, bridging the voice channel between the telecommunications switch and the central alarm monitoring station to the alarm system.
