Abstract

In one embodiment, the method of processing telephony sessions includes: communicating with an application server using an application layer protocol; processing telephony instructions with a call router; and creating call router resources accessible through a call router Application Programming Interface (API). In another embodiment, the system for processing telephony sessions includes: a call router, a URI for an application server, a telephony instruction executed by the call router, and a call router API resource.

First claim

We claim:

1. A method comprising:
receiving, by one or more processors and via a first application programming interface (API), a message comprising text, the message addressed to a recipient;
based on the recipient of the message, identifying a uniform resource locator (URL); and
sending a request to an application using a second API and via the identified URL, the request comprising the text of the message and a cryptographic hash computed from parameters of the request.

2. The method of claim 1 , wherein the receiving of the message comprises receiving a Short Message Service (SMS) message.

3. The method of claim 1 , wherein the receiving of the message comprises receiving a Multimedia Messaging Service (MMS) message.

4. The method of claim 1 , wherein the receiving of the message comprises receiving an email.

5. The method of claim 1 , wherein the request further includes an originating phone number of the received message.

6. The method of claim 1 , further comprising:
receiving, from the application, a response that includes at least one telephony instruction; and
executing, based the at least one telephony instruction, a telephony action.

7. A system comprising:
one or more processors; and
a memory coupled to the one or more processors and storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
receiving, via a first application programming interface (API), a message comprising text, the message addressed to a recipient;
based on the recipient of the message, identifying a uniform resource locator (URL); and
sending a request to an application using a second API and via the identified URL, the request comprising the text of the message and a cryptographic hash computed from parameters of the request.

8. The system of claim 7 , wherein the receiving of the message comprises receiving a Short Message Service (SMS) message.

9. The system of claim 7 , wherein the receiving of the message comprises receiving a system Messaging Service (MMS) message.

10. The system of claim 7 , wherein the receiving of the message comprises receiving an email.

11. The system of claim 7 , wherein the request further includes an originating phone number of the received message.

12. The system of claim 7 , wherein the operations further comprise:
receiving, from the application, a response that includes at least one telephony instruction; and
executing, based the at least one telephony instruction, a telephony action.

13. A non-transitory machine-readable medium that stores instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
receiving, via a first application programming interface (API), a message comprising text, the message addressed to a recipient;
based on the recipient of the message, identifying a uniform resource locator (URL); and
sending a request to an application using a second API and via the identified URL, the request comprising the text of the message and a cryptographic hash computed from parameters of the request.

14. The non-transitory machine-readable medium of claim 13 , wherein the receiving of the message comprises receiving a Short Message Service (SMS) message.

15. The non-transitory machine-readable medium of claim 13 , wherein the receiving of the message comprises receiving a system Messaging Service (MMS) message.

16. The non-transitory machine-readable medium of claim 13 , wherein the receiving of the message comprises receiving an email.

17. The non-transitory machine-readable medium of claim 13 , wherein the request further includes an originating phone number of the received message.

18. The non-transitory machine-readable medium of claim 13 , wherein the operations further comprise:
receiving, from the application, a response that includes at least one telephony instruction; and
executing, based the at least one telephony instruction, a telephony action.
