A method for delivery of alarm system event data and audio, comprising: detecting, by an alarm system, an alarm event; communicating, by the alarm system, alarm event data to a private telecommunications switch, the alarm event data being representative of the alarm event; communicating, by the private telecommunications switch, the alarm event data to a message processing gateway; 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; instructing, by the message processing gateway, the private telecommunications switch to contact a central alarm monitoring station if the alarm system is deemed registered among the known group of alarm systems serviced by the message processing gateway; in response to the instructions to contact the central alarm monitoring station, opening, by the private telecommunications switch, a Public Switched Telephone Network (PSTN) voice channel between the private telecommunications switch and the central alarm monitoring station and communicating the alarm event data to the central alarm monitoring station; determining, by the private telecommunications switch, whether the PSTN voice channel between the private telecommunications switch and the central alarm monitoring station remains open after communication of the alarm event data to the central alarm monitoring station; and in response to determining that the PSTN voice channel between the private telecommunications switch and the central alarm monitoring station remains open, bridging, by the private telecommunications switch, the PSTN voice channel between the private telecommunications switch and the central alarm monitoring station to the alarm system, to create a voice channel between the alarm system and the central alarm monitoring station.
