Abstract

A method for facilitating communication in a Session Initiation Protocol (SIP) environment is provided that includes receiving, by a first endpoint, dialog and presence information associated with a second endpoint. The first and second endpoints are operable to conduct a SIP communication system. The method also includes identifying the dialog and presence information associated with the second endpoint.

Claims

1. A method for facilitating communications in a Session Initiation Protocol (SIP) environment, comprising:

receiving, by a first endpoint, dialog and presence information, wherein the first and second endpoints are operable to conduct a SIP communication system, and wherein the dialog and presence information is associated with the second endpoint.

2. The method of claim 1, further comprising:

performing a selected one of a plurality of operations after reviewing the dialog and presence information, wherein the selected operation is one of a call setup operation, a call pickup operation, and a call barge operation.

3. The method of claim 1, further comprising:

displaying the dialog and presence information for the second endpoint.

4. The method of claim 1, wherein the second endpoint is part of a called persons list or a covered persons list that is part of a pre-defined group.

5. The method of claim 1, wherein the second endpoint is part of a called persons list or a covered persons list, which were generated dynamically.

6. The method of claim 1, further comprising:

participating in the SIP communication session that involves the second endpoint after reviewing the dialog and presence information.

7. The method of claim 1, further comprising:

inviting one or more additional endpoints to participate in the SIP communication session, wherein additional dialog and presence information associated with the additional endpoints may be provided to the first endpoint.

8. An apparatus for communicating data in a Session Initiation Protocol (SIP) environment, comprising:

a first endpoint operable to receive dialog and presence information associated with a second endpoint, wherein the first and second endpoints are operable to conduct a SIP communication system.

9. The apparatus of claim 8, wherein the first endpoint is further operable to perform a selected one of a plurality of operations after reviewing the dialog and presence information, and wherein the selected operation is one of a call setup operation, a call pickup operation, and a call barge operation.

10. The apparatus of claim 8, wherein the first endpoint is further operable to display the dialog and presence information of the second endpoint.

11. The apparatus of claim 8, wherein the second endpoint is part of a called persons list or a covered persons list that is part of a pre-defined group.

12. The apparatus of claim 8, wherein the second endpoint is part of a called persons list or a covered persons list, which were generated dynamically.

13. The apparatus of claim 8, wherein the first endpoint is further operable to participate in the SIP communication session that involves the second endpoint after reviewing the dialog and presence information.

14. The apparatus of claim 8, wherein the first endpoint is further operable to invite one or more additional endpoints to participate in the SIP communication session, wherein additional dialog and presence information associated with the additional endpoints may be provided to the first endpoint.

15. Software for facilitating communication in a Session Initiation Protocol (SIP) environment, the software being embodied in a computer readable medium and comprising computer code such that when executed is operable to:

receive, at a first endpoint, dialog and presence information, wherein the first and second endpoints are operable to conduct a SIP communication system, and wherein the dialog and presence information is associated with the second endpoint.

16. The medium of claim 15, wherein the code is further operable to:

perform a selected one of a plurality of operations after reviewing the dialog and presence information, wherein the selected operation is one of a call setup operation, a call pickup operation, and a call barge operation.

17. The medium of claim 15, wherein the code is further operable to:

display the dialog and presence information for the second endpoint.

18. The medium of claim 15, wherein the second endpoint is part of a called persons list or a covered persons list that is part of a pre-defined group.

19. The medium of claim 15, wherein the second endpoint is part of a called persons list or a covered persons list, which were generated dynamically.

20. The medium of claim 15, wherein the code is further operable to:

participate in the SIP communication session that involves the second endpoint after reviewing the dialog and presence information.

21. The medium of claim 15, wherein the code is further operable to:

invite one or more additional endpoints to participate in the SIP communication session, wherein additional dialog and presence information associated with the additional endpoints may be provided to the first endpoint.
