Abstract

A Session Initiation Protocol (SIP) message adapted for communication between a plurality of network elements located on a multi-media services provider system to form a multi-media communication path between at least a first communication device and at least a second communication device of a plurality of communication devices. The SIP message includes a header region and a plurality of header fields located on the header region. The plurality of header fields include predetermined address information associated with at least one network element of the plurality of network elements located on the multi-media services provider system.

Claims

1. A non-transitory computer-readable medium having stored thereon a plurality of instructions, the plurality of instructions including instructions which, when executed by a processor, cause the processor to perform a method for communicating between a plurality of network elements to form a multi-media communication path between a first communication device and a second communication device of a plurality of communication devices, comprising:

receiving a session initiation protocol message to form a multi-media communication path between the first communication device in communication with a first private branch exchange and the second communication device in communication with a second private branch exchange, wherein the session initiation protocol message comprises;

a header region; and

a plurality of header fields located on the header region, wherein the plurality of header fields includes predetermined address information associated with at least one network element of the plurality of network elements, wherein the plurality of header fields includes to;

header field having a collected address header parameter and a carrier identifier code header parameter in the to;

header field, wherein the carrier identifier code is for selecting a carrier for a session;

processing the session initiation protocol message; and

transmitting a second message to form the multi-media communication path between the first communication device and the second communication device.

2. The non-transitory computer readable medium of claim 1, wherein the to:

header field further comprises a collected address-nature of number header parameter.

3. The non-transitory computer readable medium of claim 2, wherein the to:

header field further comprises a collected address-numbering plan header parameter.

4. The non-transitory computer readable medium of claim 1, wherein the to:

header field further comprises a carrier selection header parameter.

5. The non-transitory computer readable medium of claim 4, wherein the to:

header field further comprises a nature of carrier header parameter.

6. The non-transitory computer readable medium of claim 1, wherein the plurality of header fields further comprises a from:

header field having a charge number header parameter.

7. The non-transitory computer readable medium of claim 6, wherein the from:

header field further comprises a charge number-nature of number header parameter.

8. The non-transitory computer readable medium of claim 7, wherein the from:

header field further comprises a charge number numbering plan header parameter.

9. The non-transitory computer readable medium of claim 8, wherein the from:

header field further comprises a calling party station type header parameter.

10. A method for communicating between a plurality of network elements to form a multi-media communication path between a first communication device and a second communication device of a plurality of communication devices, comprising:

receiving a session initiation protocol message to form a multi-media communication path between the first communication device in communication with a first private branch exchange and the second communication device in communication with a second private branch exchange, wherein the session initiation protocol message comprises;

a header region; and

a plurality of header fields located on the header region, wherein the plurality of header fields includes predetermined address information associated with at least one network element of the plurality of network elements, wherein the plurality of header fields includes a to;

header field having a collected address header parameter and a carrier identifier code header parameter in the to;

header field, wherein the carrier identifier code is for selecting a carrier for a session;

processing the session initiation protocol message; and

transmitting a second message to form the multi-media communication path between the first communication device and the second communication device.

11. The method of claim 10, wherein the to:

header field further comprises a collected address-nature of number header parameter.

12. The method of claim 11, wherein the to:

header field further comprises a collected address-numbering plan header parameter.

13. The method of claim 10, wherein the to:

header field further comprises a carrier selection header parameter.

14. The method of claim 13, wherein the to:

header field further comprises a nature of carrier header parameter.

15. The method of claim 10, wherein the plurality of header fields further comprises a from:

header field having a charge number header parameter.

16. The method of claim 15, wherein the from:

header field further comprises a charge number-nature of number header parameter.

17. The method of claim 16, wherein the from:

header field further comprises a charge number numbering plan header parameter.

18. The method of claim 17, wherein the from:

header field further comprises a calling party station type header parameter.

19. An apparatus for communicating between a plurality of network elements to form a multi-media communication path between a first communication device and a second communication device of a plurality of communication devices, comprising:

a processor; and

a computer-readable medium in communication with the processor, wherein the computer-readable medium has stored thereon a plurality of instructions, the plurality of instructions including instructions which, when executed by the processor, cause the processor to perform a method, comprising;

receiving a session initiation protocol message to form a multi-media communication path between the first communication device in communication with a first private branch exchange and the second communication device in communication with a second private branch exchange, wherein the session initiation protocol message comprises;

a header region; and

a plurality of header fields located on the header region, wherein the plurality of header fields includes predetermined address information associated with at least one network element of the plurality of network elements, wherein the plurality of header fields includes to;

header field having a collected address header parameter and a carrier identifier code header parameter in the to;

header field, wherein the carrier identifier code is for selecting a carrier for a session;

processing the session initiation protocol message; and

transmitting a second message to form the multi-media communication path between the first communication device and the second communication device.

20. The apparatus of claim 19, wherein the to:

header field further comprises a collected address-nature of number header parameter.
