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.

Claims

1. A method comprising:

associating, by a telephony application system, an application server with a recipient identifier;

establishing, by a call router of the telephony application system, a telephony session of the recipient identifier;

associating, by the telephony application system, the recipient identifier with a uniform resource identifier (URI) of the application system server;

providing, by the telephony application system, information of the telephony session to the application server via the URI over a network;

receiving, by the telephony application system, a telephony instruction from the application server responsive to the information of the telephony session; and

executing, by the telephony application system, an action for the telephony session based on the telephony instruction.

2. The method of claim 1, wherein the telephony session is a voice session.

3. The method of claim 1, wherein the telephony session is a messaging session.

4. The method of claim 1, further comprising:

associating, by the telephony application system, a second application server with a second recipient identifier of the telephony application system;

providing, by the telephony application system, information of a second telephony session of the second recipient identifier to the second application server via the network;

receiving, by the telephony application system, a second telephony instruction from the second application server responsive to the information of the second telephony session; and

executing, by the telephony application system, a second action for the second telephony session based on the second telephony instruction.

5. The method of claim 1, further comprising:

receiving, by the telephony application system, a second telephony instruction from the application server responsive to the information of the telephony session; and

executing, by the telephony application system, a second action for the telephony session based on the second telephony instruction.

6. The method of claim 1 where the application server is external to the telephony application system.

7. A system comprising:

one or more processors configured to perform operations comprising;

associating an application server with a recipient identifier;

establishing a telephony session of the recipient identifier by using a call router;

associating the recipient identifier with a uniform resource identifier (URI) of the application server;

providing information of the telephony session to the application server via the URI over a network;

receiving a telephony instruction from the application server responsive to the information of the telephony session; and

executing an action for the telephony session based on the telephony instruction.

8. The system of claim 7, further comprising:

the application server.

9. The system of claim 7, further comprising:

a plurality of application servers including the application server.

10. The system of claim 7, wherein the telephony session is a voice session.

11. The system of claim 7, wherein the telephony session is a messaging session.

12. The system of claim 7, wherein the executing of the action for the telephony session based on the telephony instruction comprises executing a voicemail action.

13. The system of claim 7, wherein the executing of the action for the telephony session based on the telephony instruction comprises executing a customer service action.

14. The system of claim 7, wherein the executing of the action for the telephony session based on the telephony instruction comprises executing a notification action.

15. The system of claim 7, wherein the executing of the action for the telephony session based on the telephony instruction comprises executing a PBX action.

16. The system of claim 7, wherein the executing of the action for the telephony session based on the telephony instruction comprises executing a CRM action.

17. The system of claim 7, wherein the executing of the action for the telephony session based on the telephony instruction comprises executing a call queue action based.

18. A method comprising:

associating, by a call router system, an application server with a recipient identifier;

associating, by the call router system, the recipient identifier with a uniform resource identifier (URI) of the application server;

providing, by the call router system, information of a telephony session of the recipient identifier to the application server via the URI over a network;

receiving, by the call router system, a telephony instruction from the application server responsive to the information of the telephony session; and

executing, by the call router system, an action for the telephony session based on the telephony instruction.

19. The method of claim 18, wherein the telephony session is a voice session.

20. The method of claim 18, wherein the telephony session is a messaging session.
