Abstract

A system and method for establishing a SIP session between calling and called end-points. A SIP server receives a SIP INVITE request for establishing the SIP session. The SIP INVITE request includes standard routing information in its header. The SIP server receives the SIP INVITE request and responds by transmitting to the calling end-point a HTML link associated with a web server. In rendering the contents of the HTML link, the calling end-point transmits an HTTP request to the web server including voice cookie information. The voice cookie information may include information gathered about the caller such as the caller profile information, transaction information, caller intent information, or recent and past history associated with a web site domain. The web server forwards the voice cookies to the SIP server. The SIP server determines an address of the called end-point as a function of the routing information in the SIP INVITE request and the voice cookie information. The call is then routed to the determined address along with the voice cookies or information derived from the voice cookies. New voice cookies may be written to the web server which transmits these to the calling end-point within an HTTP response.

Claims

1. A method for establishing a session initiation protocol (SIP) session between a first device and a second device, the method comprising the steps of:

receiving a call establishment message from the first device for establishing the SIP session;

retrieving information stored in the first device in response to the call establishment message;

determining an address of the second device based on the retrieved information; and

using the address for routing the SIP session to the second device.

2. The method of claim 1, wherein the information includes information gathered about a user of the first device.

3. The method of claim 2, wherein the information includes information from interactions of the user with a particular web site.

4. The method of claim 1, wherein the step of retrieving the information comprises the step of retrieving the information by the first device for transmitting to a web server.

5. The method of claim 4 further comprising the step of receiving the information from the web server.

6. The method of claim 1 further comprising the step of writing new information in the first device for use in routing future SIP sessions initiated by the first device.

7. The method of claim 1 further comprising the step of transmitting the retrieved information to the second device.

8. A method for establishing a session initiation protocol (SIP) session between a first device and a second device, the method comprising the steps of:

receiving a call establishment message from the first device for establishing the SIP session;

transmitting an address of a server to the first device for causing retrieval of information stored in the first device;

receiving the retrieved information from the first device;

determining an address of the second device based on the retrieved information; and

using the address for routing the SIP session to the second device.

9. The method of claim 8, wherein the information includes information gathered about a user of the first device.

10. The method of claim 9, wherein the information includes interactions of the user with a particular web site.

11. The method of claim 8 further comprising the step of writing new information in the first device for use in routing future SIP sessions initiated by the first device.

12. The method of claim 8, wherein the address is associated with a hypertext markup language link.

13. The method of claim 8, wherein the address is transmitted in a response SIP message to the first device.

14. The method of claim 8 further comprising the step of transmitting the retrieved information to the second device.

15. A method for establishing a session initiation protocol (SIP) session between a first device and a second device, the method comprising the steps of:

receiving a call establishment message from the first device;

retrieving caller intent information from a data store on the first device in response to the call establishment message;

using the caller intent information to determine an address of the second device; and

using the address for routing the SIP session to the second device.

16. The method of claim 15, wherein the caller intent information includes caller data.

17. The method of claim 15 further comprising the step of writing new caller intent information in the data store for use in routing future SIP sessions initiated by the first device.
