Abstract

A method and system for scheduling a conference call using a packet-network telephone in which a user interface of the packet-network telephone (i) is provided with a user directory that comprises a list of potential conference call participants that are selectable via the user interface, (ii) receives from the user interface, a selection of one or more persons selected from the user directory list to participate in the conference call, and (iii) transmit a signaling protocol message from the packet-network telephone to a packet-network, where the signaling protocol message is destined for a serving device for scheduling the conference call. The signaling protocol message comprises a request to schedule the conference call and a respective identifier for each of the one or more persons selected from the user directory to participate in the conference call.

Claims

1. A method for using a packet-network telephone to schedule a conference call, the method comprising:

providing to a user interface of a packet-network telephone, a user directory accessible via the user interface, wherein the user directory comprises a list of potential conference call participants that are selectable via the user interface;

receiving from the user interface, a selection of one or more persons from the user directory, wherein the one or more persons are selected to participate in a conference call; and

transmitting a first signaling protocol message from the packet-network telephone to a packet-network, wherein the first signaling protocol message is destined for a serving device, and wherein the first signaling protocol message comprises (i) a request to schedule the conference call, and (ii) a respective identifier for each of the one or more persons selected to participate in the conference call.

2. The method of claim 1, wherein the first signaling protocol message comprises a Session Initiation Protocol (SIP) message.

3. The method of claim 2, wherein the SIP message comprises a SIP OPTIONS message.

4. The method of claim 2, wherein the SIP message comprises a SIP NOTIFY message.

5. The method of claim 2, wherein the request to schedule the conference call and the respective identifier for each of the one or more persons selected to participate in the conference call are arranged according to an Extensible Markup Language (XML).

6. The method of claim 1, wherein the first signaling protocol messages comprises an H.323 message.

7. The method of claim 1, wherein the first signaling protocol message further comprises an identifier associated with a user of the packet-network telephone.

8. The method of claim 1, further comprising:

receiving from the user interface, a conference start time and a conference date,

wherein the first signaling protocol message further comprises the conference start time and the conference date.

9. The method of claim 8, further comprising:

establishing a communication session between the packet-network telephone and the serving device so that a user of the packet-network telephone can participate in the conference call,

wherein establishing the communication session comprises receiving from the serving device a second signaling protocol message, and

wherein the serving device transmits the second signaling protocol message upon occurrence of the conference start time on the conference date.

10. The method of claim 9, wherein the second signaling protocol message comprises a SIP INVITE message.

11. The method of claim 9, wherein the conference call is carried out between the packet-network telephone and one or more other packet-network telephones that are associated with the one or more persons selected to participate in the conference call.

12. The method of claim 8, further comprising:

receiving from the user interface, data for use in determining a conference end time,

wherein the data for use in determining the conference end time is data selected from the group consisting of (i) a given time that is later than the conference start time, and (ii) a time duration, and

wherein the first signaling protocol message further comprises the data for use in determining the conference end time.

13. The method of claim 1, wherein the serving device comprises a conference serving device that schedules the conference call upon receiving the first signaling protocol message that comprises the request to schedule the conference call.

14. The method of claim 1, wherein providing to a user interface of a packet-network telephone, a user directory accessible via the user interface, comprises:

sending a second signaling protocol message from the packet-network telephone to the serving device, wherein the second signaling protocol message comprises a request for the serving device to send at least a portion of the user directory to the packet-network telephone; and

receiving at the packet-network telephone, a third signaling protocol message that comprises the at least a portion of the user directory.

15. A method for using a packet-network telephone to schedule a conference call, the method comprising:

providing to a user interface of a Signaling Interface Protocol (SIP)-based packet-network telephone, a user directory accessible via the user interface, wherein the user directory comprises a list of potential conference call participants that are selectable via the user interface, and wherein the user directory is provided to the SIP-based packet-network telephone via at least a first SIP message;

receiving from the user interface of the SIP-based packet-network telephone, a selection of one or more persons from the user directory, wherein the one or more persons are selected to participate in a conference call; and

transmitting a second SIP message from the SIP-based packet-network telephone to a packet-network, wherein the second SIP message is destined for a SIP-based serving device, and wherein the second SIP message comprises (i) a request to schedule the conference call, and (ii) a respective identifier for each of the one or more persons selected to participate in the conference call.

16. The method of claim 15, wherein the first SIP message comprises a SIP message selected from the group consisting of (i) a first SIP NOTIFY message, and (ii) a first SIP OPTIONS message, and wherein the second SIP message comprises a SIP message selected from the group consisting of (i) a second SIP NOTIFY message, and (ii) a second SIP OPTIONS message.

17. The method of claim 16, further comprising:

entering a conference start time, a conference date, and data for use in determining a conference end time, via the user interface of the SIP-based packet-network telephone;

wherein the second SIP message further comprises the conference start time, the conference date, and the data for use in determining the conference end time.

21. The packet-network telephone of claim 15, wherein the user interface comprises a display to provide the user directory at the user interface.

18. A packet-network telephone for scheduling a conference call, the packet-network telephone comprising:

a user interface;

a processor; and

data storage comprising instructions executable by the processor for causing the packet-network telephone to;

provide to the user interface, a user directory accessible via the user interface, wherein the user directory comprises a list of potential conference call participants that are selectable via the user interface;

receive from the user interface, a selection of one or more persons from the user directory, wherein the one or more persons are selected to participate in a conference call; and

transmit a first signaling protocol message to a packet-network, wherein the first signaling protocol message is destined for a serving device, and wherein the first signaling protocol message comprises (i) a request to schedule the conference call, and (ii) a respective identifier for each of the one or more persons selected to participate in the conference call.

19. The packet-network telephone of claim 18, wherein the user interface comprises means for entering a conference start time and a conference date, and wherein the first signaling protocol message further comprises the conference start time and the conference date.

20. The packet-network telephone of claim 19, further comprising a packet-network interface,

wherein the data storage further comprises instructions executable by the processor for causing the packet-network telephone to process a second signaling protocol message received at the network interface, wherein the second signaling protocol message initiates setting up a communication session between the packet-network telephone and the serving device for use during the conference call.
