Abstract

A method, apparatus, and computer program product for flexibly assigning Session Initiation Protocol (SIP) Endpoints to any part of a communication resource is disclosed. The present invention removes the device location and behavior requirements from the application, thus providing a generic interface for robust application development.

Claims

1. A method for Session Initiation Protocol (SIP) based communications comprising:

providing a plurality of SIP endpoints;

providing an SIP enabled device; and

assigning at least two of said plurality of SIP endpoints to said SIP enabled device.

2. The method of claim 1 further comprising:

defining a first event associated with at least one of said assigned SIP endpoints;

detecting an occurrence of said first event;

performing a first response upon detecting said occurrence of said first event.

3. The method of claim 2, wherein said first event is one of:

receiving an SIP message on at least one of said assigned SIP endpoints;

or

an expiration of a logical timer.

4. The method of claim 2, wherein said response is one of:

sending at least one message from at least one of said assigned SIP endpoints;

defining a second event associated with at least one of said assigned SIP endpoints;

or

setting a logical timer.

5. The method of claim 2, further comprising:

providing at least one user interface point;

defining a second event associated with one of said at least one user interface point;

detecting an occurrence of said second event;

performing a second response upon detecting said occurrence of said second event.

6. The method of claim 5, wherein said first response or said second response, is one of:

sending a message to one of said at least one user interface point;

or

sending at least one SIP message from at least one of said assigned SIP endpoints.

7. An apparatus comprising:

a Session Initiation Protocol (SIP) enabled device suited to perform SIP based communications; and

a plurality of SIP endpoints, wherein at least two of said plurality of SIP endpoints are assigned to said SIP enabled device.

8. The apparatus of claim 7, wherein a first event associated with at least one of said assigned SIP endpoints is defined and upon detection of an occurrence of said first event, a first response is performed.

9. The apparatus of claim 8, wherein said first event is one of:

receiving at least one SIP message on at least one of said assigned SIP endpoints;

or

an expiration of a logical timer.

10. The apparatus of claim 8, wherein said first response is one of:

sending at least one SIP message from at least one of said assigned SIP endpoints;

defining a second event associated with at least one of said assigned SIP endpoints;

or

setting a logical timer.

11. The apparatus of claim 8 further comprising:

at least one user interface point, wherein a second event is defined, which is associated with one of said at least one user interface point, and upon detecting an occurrence of said second event, a second response is performed.

12. The apparatus of claim 11, wherein said first response or said second response is one of:

sending a message to one of said at least one user interface point;

or

sending at least one SIP message from at least one of said assigned SIP endpoints.

13. A computer program product comprising a computer usable medium having computer readable program code embodied therein configured to:

communicate in Session Initiation Protocol (SIP) based communications using a plurality of SIP endpoints, wherein at least two of said plurality of SIP endpoints are assigned to a single SIP enabled device.

14. The computer program product of claim 13, wherein the computer readable program code is further configured to:

define a first event, which is associated with at least one of said assigned SIP endpoints;

detect an occurrence of said first event; and

perform a first response upon detecting said occurrence of said first event.

15. The computer program product of claim 14, wherein the computer readable program code is configured to define said first event that is one of:

receiving at least one SIP message on at least one of said assigned SIP endpoints;

or

an expiration of a logical timer.

16. The computer program product of claim 14, wherein the computer readable program code is configured to perform said first response that is one of:

sending at least one SIP message from at least one of said assigned SIP endpoints;

defining a second event associated with at least one of said assigned SIP endpoints;

or

setting a logical timer.

17. The computer program product of claim 14, wherein the computer readable program code is further configured to:

define a second event associated with one of said at least one user interface point;

detect an occurrence of said second event; and

perform a second response upon detecting said occurrence of said second event.

18. The computer program product of claim 17, wherein said first response or said second response is one of:

sending a message to one of said at least one user interface point;

or

sending at least one SIP message from at least one of said assigned SIP endpoints.
