1. A method, comprising:
- providing a plurality of voice communications terminals within a premises serviced by a contact processing switch or server, each of the voice communications terminals having a corresponding internal telephone extension, wherein the voice communications terminals are operable to receive incoming telephone calls to the internal telephone extensions and send outgoing telephone calls to the contact processing switch or server, wherein the contact processing switch or server directs incoming telephone calls to and receives outgoing telephone calls from the internal telephone extensions;
receiving, by a first selected voice communications terminal, an audio stream through a microphone when the first selected voice communications terminal is not engaged in a telephone call;
determining, by the first selected voice communications terminal, that the audio stream comprises nonbackground audio signals;
in response to determining that the audio stream comprises the nonbackground audio signals, at least one of notifying, by the first selected voice communications terminal, the contact processing switch or server and providing, by the first selected voice communications terminal, at least a portion of the audio stream to the contact processing switch or server;
receiving, by a second selected voice communications terminal, the audio stream through a microphone when the second selected voice communications terminal is not engaged in a telephone call;
determining, by the second selected voice communications terminal, that the audio stream comprises nonbackground audio signals;
in response to determining, by the second selected voice communications terminal, that the audio stream comprises the nonbackground audio signals, at least one of notifying, by the second selected voice communications terminal, the contact processing switch or server and providing, by the second selected voice communications terminal, at least a portion of the audio stream to the contact processing switch or server;
determining, by the contact processing switch or server, an approximate physical location of a source for the audio stream based on a first physical location of the first selected voice communications terminal and a second physical location of the second selected voice communications terminal;
forwarding, by the first selected voice communications terminal, at least a portion of the audio stream to the contact processing switch or server.

9. A voice communications terminal, comprising:
-
a microphone operable to receive an audio stream when the voice communications terminal is not engaged in a telephone call; a corresponding internal telephone extension in a premises serviced by a contact processing server, wherein the voice communications terminal is operable to receive incoming telephone calls to the internal telephone extension and send outgoing telephone calls to the contact processing switch or server, the contact processing server directing incoming telephone calls to and receiving outgoing telephone calls from the internal extension; a voice activity detector operable to determine that the audio stream comprises nonbackground signals and in response to determining that the audio stream comprises the nonbackground signals, at least one of notify the contact processing server and provide at least a portion of the audio stream to the contact processing server; wherein the voice communications terminal has a known physical location within a building, wherein the known physical location is unique to the voice communications terminal and different from a known physical location of one or more other voice communications terminals in the building, and wherein an approximate location of the audio stream is determined based on the known physical location of at least two voice communication terminals; an audio broadcasting agent operable to receive at least one of a text and audio message from the contact processing server and broadcast the at least one of a text and audio message through a speaker. - View Dependent Claims (10, 11, 12, 13, 14)

15. A communications system, comprising:
-
two or more voice communications terminals, wherein each voice communications terminal has a corresponding known physical location within a building, each voice communications terminal comprising; an input operable to receive an audio stream when the voice communications terminal is not engaged in a telephone call; a corresponding internal telephone extension in a premises serviced by a communications server, wherein the voice communications terminals are operable to receive incoming telephone calls to the internal telephone extension and send outgoing telephone calls to the communications server; a voice activity detector operable to determine that the audio stream comprises voice signals and in response to determining that the audio stream comprises voice signals, operable to at least one of notify the communications server and provide at least a portion of the audio stream to the communications server, wherein the voice activity detector is operable to determine whether an audio stream comprises nonbackground signals by identifying audio signals that, based on the audio signal frequency range or distribution, are unusual relative to background audio signals received over a determined time interval or the background audio signals having a signal strength greater than a selected decibel level, wherein the two or more voice communications terminals are telephones, and further operable to determine a physical location of one of the two or more voice communications terminals by mapping a corresponding extension of the one of the two or more voice communications terminals to a corresponding electronic network address and mapping the corresponding network address to determine the physical location; and the communications server in communication with the two or more voice communications terminals, the communications server operable to receive one or more notifications from one or more voice communications terminals, and operable to transmit an alarm notification to a security provider, the communications server comprising; a call controller operable to direct incoming telephone calls to and receive outgoing telephone calls from the corresponding internal telephone extensions, operable to receive the notification from the voice communications terminals, and operable to transmit an alarm notification to a security provider. - View Dependent Claims (16, 17, 18, 19)
