Abstract

An IP-enabled speaker with a trigger button module. Activation of the button on the trigger button module activates an audio link between a user of the speaker and a user of a destination communications device.

Claims

1. A device for use in communicating with a Mass Notification Management Center (MNMC), the device comprising:

a trigger button module comprising a first microphone and at least one activatable button;

a remote speaker comprising a second microphone, the speaker for producing audio audible to a user of said device;

a connector connecting the trigger button module to the speaker;

wherein said speaker is Internet Protocol (IP) capable and is remotely controllable to produce said audio;

wherein said device is intended for mass audio communications;

wherein said trigger button module triggers at least one predefined action related to communications between said speaker and a destination communications device,

wherein said communications comprises placing a call between said speaker and said destination communications device using an IP link establishment protocol;

wherein said speaker communicates status of said trigger button module to said MNMC;

wherein a Uniform Resource Identifier (URI) is accessed when said at least one activatable button is activated;

wherein the speaker receives an audio message sent to a plurality of speakers;

and wherein

either the first microphone or the second microphone is used depending on at least one of;

(1) state of the trigger button module, and

(2) state of said corresponding speaker connected to the trigger button module.

2. A device according to claim 1 wherein an activation of at least one activatable button executes a command related to said communications between said speaker and said destination communications device.

3. A device according to claim 2 wherein an activation of said at least one activatable button activates an audio link between said device and a live operator.

4. A device according to claim 2 wherein an activation of said at least one activatable button activates an audio link between said device and a user of a mass notification system, said MNMC being a component of said mass notification system.

5. A device according to claim 2 wherein said speaker further comprises a control module for controlling functions of said trigger button module;

wherein said control module selects between said first microphone and said second microphone when an active audio connection is initiated,

said selecting based on one of;

(1) state of the trigger button module,

(2) state of the speaker, and

(3) noise level of either the first or second microphone.

8. A device according to claim 2, wherein said internet protocol (IP) link establishment protocol is the Session Initiation Protocol;

said MNMC provisions the handling of activation of the at least one activatable button; and

said provisioning is stored.

11. The device of claim 1, wherein said device is deployed at a location within either an enterprise or a campus.

6. A method for initiating a communications link between a speaker and a destination client device:

said speaker one of a plurality of speakers being intended for mass audio communications;

the method comprising;

a) detecting, by the speaker, an activation of a trigger button on a remote trigger button module;

b) transmitting a setup communication from said speaker to a management server, said setup communication being in compliance with an IP link establishment protocol;

c) receiving an alert communication from said destination client device;

d) activating a microphone of the trigger button module for a user at a location of said speaker, said speaker comprising a second microphone;

e) establishing an audio communications path between said speaker and said destination client device, said audio communications path established being in compliance with an IP link establishment protocol; and

f) communicating status of said trigger button module to said management server;

wherein a Uniform Resource Identifier (URI) is accessed when said trigger button is activated; and

wherein either the first microphone or the second microphone is used depending on at least one of;

(1) state of the trigger button module, and

(2) state of said corresponding speaker.

7. A method according to claim 6 wherein said destination client device is used by a live operator such that a user of said speaker is in voice communication with said live operator after said audio communication path is established.

9. A method according to claim 6, wherein said internet protocol (IP) link establishment protocol is the Session Initiation Protocol, and further comprising:

g) communicating to the MNMC that the trigger button module is present.

10. A method according to claim 9, wherein said internet protocol (IP) link establishment protocol uses H.323 style link establishment primitives, and further comprising:

h) provisioning the handling of activation of the trigger button; and

i) storing said provisioning in a speaker profile.

12. A mass audio notification system comprising:

a Mass Notification Management Center (MNMC);

a plurality of destination communication devices connected to said MNMC via a network;

a plurality of speakers interconnected with said MNMC via said network,

wherein each of said plurality of speakers is Internet Protocol (IP) capable and is remotely controllable to produce audio, and

wherein each of said plurality of speakers receives an audio message from the MNMC for mass audio communications; and

a corresponding one or more remote trigger button modules connected to a corresponding one of said plurality of speakers, each of the one or more trigger button modules coupled to a corresponding speaker using a connector,

wherein said corresponding one or more trigger button modules triggers at least one predefined action related to communications between the corresponding speaker and said at least one of the plurality of destination communications devices,

wherein said communications comprise;

establishing an audio link between said corresponding speaker and said at least one destination communications device using an IP link establishment protocol, and

placing at least one call over an audio link between said corresponding speaker and said at least one destination communications devices and

wherein each of said corresponding one or more trigger button modules comprises at least one activatable button;

wherein a Uniform Resource Identifier (URI) is accessed when said at least one activatable button is activated;

wherein one of said corresponding one or more trigger button modules comprises a microphone; and

wherein said corresponding speaker comprises a second microphone; and

either the first microphone or the second microphone is used depending on at least one of;

(1) state of the one of said corresponding one or more trigger button modules, and

(2) state of said corresponding speaker.

13. The system of claim 12 wherein said plurality of speakers is deployed in a plurality of locations around a campus, and said corresponding speaker communicates statuses of said corresponding one or more trigger button modules to said MNMC.

14. The system of claim 13 wherein said corresponding one or more trigger button modules are used to signal security associated with said campus.

15. The system of claim 13, wherein said destination communications devices comprises one or more client devices;

and

said MNMC receives one or more instructions from said one or more client devices to broadcast one or more audio messages to said plurality of speakers.

16. The system of claim 15, wherein said plurality of speakers comprises a plurality of subsets, and wherein each subset comprises one or more speakers;

and

said MNMC broadcasts a different audio message to each of the plurality of subsets.

17. The system of claim 12, wherein said plurality of speakers is deployed in a plurality of locations around either

(1) an enterprise, or

(2) a campus.

18. The system of claim 12, wherein said at least one predefined action comprises launching a broadcast.

19. The system of claim 12, wherein said corresponding speaker stores said placed at least one call in its entirety for future retrieval.

20. The system of claim 12,

wherein said corresponding speaker records audio activity picked up by said microphone while said audio link is being established.

21. The system of claim 12,

wherein a voice message is recorded using said microphone;

and

said voice message is transmitted.

22. The system of claim 12, wherein said transmission occurs using a file transfer.

23. The system of claim 12,

wherein

either the first microphone or the second microphone is used based on a predetermined policy.
