Abstract

A method and system for preserving session state in telephony communication including initializing a communication session of telephony communication between a telephony device and an application server; routing the telephony communication through a call router; storing session state for the communication session of the telephony device and the application server; and transmitting the stored session state in communication between the application server and the call router.

Claims

1. A method for preserving session state in telephony messaging comprising:

initializing a communication session with a telephony communication between a telephony device and an application server;

routing the telephony communication through a call router;

storing session state for the communication session of the telephony device and the application server; and

transmitting the stored session state in communication between the application server and the call router.

2. The method of claim 1, wherein a telephony communication is an SMS message.

3. The method of claim 1, wherein a telephony communication is a voice call.

4. The method of claim 1, wherein the session state is defined by a to-field and from-field.

5. The method of claim 4, wherein transmitting the stored session state includes transferring session state data through an HTTP Cookie identified from the to-field and from-field of the session state.

6. The method of claim 1, wherein data of the session state is stored as an API resource accessible through an API of the telephony platform;

and wherein transmitting the stored session state data includes transferring session state data through an API call identifying a session state by a to-field and from-field.

7. The method of claim 1, further comprising regulating communication within a communication session.

8. The method of claim 7 wherein regulating includes queuing telephony communication and rate limiting telephony communication within a communication session determined by the session state.

9. The method claim 1, wherein the telephony communication is telephony messaging;

and further comprising associating the communication session with a voice session.

10. The method of claim 9, wherein the session state is stored as an HTTP cookie, and wherein associating the communication session with a voice session further includes sharing the HTTP cookie with the voice session between the telephony device and the application server.

11. The method of claim 1, further comprising communicating a tracking link, wherein a tracking link is a link to a resource and the tracking link is unique to the communication session;

and associating access of a resource through the tracking link with the communication session.

12. The method of claim 11, wherein the tracking link is a universal resource identifier (URI) and resource access is made through a web browser;

and wherein associating resource access includes associating the browser session with the communication session.

13. The method of claim 11, wherein a telephony communication is an SMS message, and wherein the tracking link is communicated through an SMS message.

14. The method of claim 11, wherein the tracking link is communicated in an email message.

15. A method for preserving session state between plurality of communication channels comprising:

initializing a communication session between a telephony device and an application server;

assigning a unique tracking link to the communication session

communicating the tracking link; and

associating resource access made through the tracking link with the communication session.

16. The method of claim 15, wherein the communication session is a telephony voice session.

17. The method of claim 15, wherein the tracking link is a URI and resource access is made through a web browser;

and wherein associating resource access includes associating the browser session with the communication session

18. The method of claim 15, wherein the resource access includes opening an application indicated through the tracking link.

19. The method of claim 15, wherein the tracking link is communicated through an SMS message.

20. The method of claim 15, wherein the tracking link is communicated through an email message.
