Abstract

A system for establishing a unilateral voice communication event between at least two nodes connected to a network has a first server operable on the network for receiving a request from a requesting node on the network and for forwarding the request for execution, a second server operable on the network, the second server for formatting the request in the form of a sequence of commands based on information associated with the request, the command sequence to establish the event; and a third server operable on the network, the third server for receiving commands of the command sequence and for establishing the event and implementing at least one state of operation on the recipient node. The event request is initiated by a single action performed at a requesting node and the established event is automatically answered without any physical tasking required or event alert received by the recipient node.

Claims

1. A system for establishing a unilateral voice communication event between at least two nodes connected to a network the event request initiated by a single action performed at a requesting node and the established event automatically answered without any physical tasking required or event alert received by the recipient node comprising:

a first server operable on the network for receiving a request from a requesting node on the network and for forwarding the request for execution;

a second server operable on the network having communication access to the first server, the second server for formatting the request in the form of a sequence of commands based on information associated with the request, the command sequence to establish the event; and

a third server operable on the network having communication access to the second server, the third server for receiving commands of the command sequence and for establishing the event and implementing at least one state of operation on the recipient node.

2. The system of claim 1, wherein the network is a local-area-network connected to a private branch exchange.

3. The system of claim 1, wherein the network is a wide-area-network.

4. The system of claim 1, wherein the requesting node and the receiving node are private-branch-exchange (PBX) speakerphones connected to a computer-integrated-telephony (CTI)-enhanced PBX telephony switch.

5. The system of claim 1, wherein physical tasking comprises manually off hooking a handset or interacting with any feature on the recipient device and event alert includes any audible or visual indication of the event.

6. The system of claim 1, wherein the requesting node and or the receiving node are enabled for session-initiation-protocol and voice-over-Internet-protocol.

7. The system of claim 1, wherein the receiving node is a voice-enabled automated media server and the requesting node is one of one an Internet protocol telephone, a PBX telephone, a cellular telephone, a SIP phone, or a software telephony application resident on a computing appliance.

8. The system of claim 1, wherein the command sequence is a CTI command sequence executable at a PBX switch or a soft PBX switch.

9. The system of claim 1, wherein the single action performed to request the event is one of pushing a button, selecting a display icon, or voicing a command.

10. The system of claim 1, wherein presence information is returned over an established connection if a recipient is not available.

11. The system of claim 1, wherein the first server is a presentation server, the second server is an application server, and the third server is a CTI/PBX telephony server.

12. The system of claim 1, including an additional application adapted as a conferencing bridge.

13. A method for establishing a unilateral voice event between a requesting node and one a recipient node over a network including acts for:

(a) identifying, at the requesting node, the recipient node to receive the event;

(b) sending a request to an application to establish the event;

(c) executing a command sequence of instructions to build the connection over which, the event will be carried;

(d) placing a call to and answering the call at the requesting mode according to the command sequence;

(e) placing a call to and answering the call at the recipient node according to the command sequence; and

(f) bridging the established connections for active use.

14. The method of claim 13, wherein in act (a), the sending node and the recipient node are one of or are a combination of a PBX telephone, an IP telephone, a SIP telephone, a cellular telephone, or a software telephony application.

15. The method of claim 13, wherein in act (b) the request is achieved through a single user task comprising pushing of a mode button on a phone set or invoking an icon or list entry in a graphics user interface (GUI) for the duration of the event.

16. The method of claim 13, wherein in act (c), the sequence is a CTI command set.

17. The method of claim 13, wherein in act (d) and in act (e), placing and answering calls is performed by a CTI/PBX switch upon instruction from a conference bridging application.

18. The method of claim 13, wherein in act (e), answering the call includes activating the mute state of the microphone on the device to mute outgoing voice and background noise.

19. The method of claim 13, wherein in acts (d) and (e), answering the call is performed with no physical tasks required at the recipient device.

20. The method of claim 13, further including an act (g) for requesting release of the recipient node of the event from the point of the requesting node, the release action causing tear down of the connection to the one or more devices.

21. The method of claim 13, further including an act (g) for returning a message to the requesting node in the event that the user of the recipient node cannot take the event.

22. The method of claim 21, wherein the message is one of an instant message, a voice message, or a text message.

23. The method of claim 21, wherein the message includes interactive options for contacting the recipient.

24. The method of claim 13, further including an act (g) for escalating the unilateral voice session into a conventional call.

25. The method of claim 24, wherein the request for escalation is achieved through a single action performed by the requester.

26. The method of claim 25, wherein the single action is one of depressing a mode button, clicking on a PC display icon, or voicing a command.
