Abstract

Method to provide SIP session management of a real-time communication to a softphone client in a virtual machine, including: accepting an invitation to join a SIP session; receiving, by a server-based softphone in the SIP session, a real-time communication that is encoded with at least one SIP session aspect; transmitting the real-time communication and the at least one SIP session aspect to a client-based softphone; and using the at least one SIP session aspect for SIP session management.

Claims

1. A method to provide session management of a real-time communication to a softphone client in a virtual machine, via a predetermined signaling protocol, comprising:

accepting an invitation to join a session;

receiving, by a server-based softphone in the session, a real-time communication that is encoded with at least one session aspect;

transmitting the real-time communication and the at least one session aspect to a client-based softphone; and

using the at least one session aspect for session management.

2. The method of claim 1, further comprising before accepting an invitation to join the session:

registering the server-based softphone in the session with a control system; and

privately registering the client-based softphone with the server-based softphone.

3. The method of claim 1, further comprising before accepting an invitation to join session:

registering the server-based softphone in the session with a control system; and

registering the client-based softphone with the control system.

4. The method of claim 1, further comprising providing a back-to-back logical network element to transmit the real-time communication and the at least one session aspect to the client-based softphone.

5. The method of claim 1, wherein transmitting the real-time communication and the at least one session aspect comprises shuffling the real-time communication to the client-based softphone.

6. The method of claim 1, wherein transmitting the real-time communication and the at least one session aspect is by use of full signaling.

7. The method of claim 1, wherein the real-time communication is carried by a channel that does not carry signaling communication.

8. The method of claim 1, further comprising:

negotiating a media by use of the server-based softphone; and

extending an identification of the negotiated media to the client-based softphone.

9. The method of claim 1, further comprising:

negotiating a media by use of the client-based softphone.

21. The method of claim 1, wherein the predetermined signaling protocol is selected from the group consisting of SIP, H.323 and ISDN/TDM.

10. A system to provide session management of a real-time communication to a softphone client in a virtual machine, via a predetermined signaling protocol, comprising:

a receiver configured to accept an invitation to join a session;

a server-based softphone in the session configured to receive a real-time communication that is encoded with at least one session aspect;

a transmitter configured to transmit the real-time communication and the at least one session aspect to a client-based softphone; and

a session manager configured to use the at least one session aspect for session management.

11. The system of claim 10, further comprising:

a server-based module configured to register the server-based softphone in the session with a control system; and

a client-based module configured to privately register the client-based softphone with the server-based softphone.

12. The system of claim 10, further comprising:

a server-based module configured to register the server-based softphone in the session with a control system; and

a client-based module configured to register the client-based softphone with the control system.

13. The system of claim 10, further comprising a back-to-back logical network element configured to transmit the real-time communication and the at least one session aspect to the client-based softphone.

14. The system of claim 10, wherein the transmitter comprises a module configured to shuffle the real-time communication to the client-based softphone.

15. The system of claim 10, wherein the transmitter is configured to transmit the real-time communication and the at least one session aspect by use of full signaling.

16. The system of claim 10, further comprising an interface to a communication channel configured to carry signaling communication separate from the real-time communication.

17. The system of claim 10, further comprising:

a negotiation module configured to negotiate a media by use of the server-based softphone,

wherein an identification of the negotiated media is extended to the client-based softphone.

18. The system of claim 10, further comprising:

a negotiation module configured to negotiate a media by use of the client-based softphone.

22. The method of claim 10, wherein the predetermined signaling protocol is selected from the group consisting of SIP, H.323 and ISDN/TDM.

19. A system to provide session management of a real-time communication to a softphone client in a virtual machine, via a predetermined signaling protocol, comprising:

a processor;

a memory coupled to the processor, the memory configured to store software that, when executed by the processor, performs the steps of;

accepting an invitation to join a session;

receiving, by a server-based softphone in the session, a real-time communication that is encoded with at least one session aspect;

transmitting the real-time communication and the at least one session aspect to a client-based softphone; and

using the at least one session aspect for session management.

20. The system of claim 19, wherein the memory is further configured to store software that, when executed by the processor, performs the step of:

providing a back-to-back logical network element to transmit the real-time communication and the at least one session aspect to the client-based softphone.

23. The method of claim 19, wherein the predetermined signaling protocol is selected from the group consisting of SIP, H.323 and ISDN/TDM.
