Abstract

A method for processing telephony sessions of a network including at least one application server and a call router, the method including the steps of assigning a primary Uniform Resource Identifier (URI) and at least a secondary URI to an application; mapping a telephony session to the primary URI; communicating with the application server designated by the primary URI using an application layer protocol; receiving telephony instructions from the application server and processing the telephony instructions with the call router; detecting an application event; and upon detecting the application event, communicating with the application server designated by the secondary URI.

First claim

We claim:

1. A method comprising:
receiving, via a settings interface, a first Uniform Resource Identifier (URI) associated with an application and a second URI associated with the application;
in response to receiving an incoming communication request directed to a first communication address associated with a first account, communicating with the application using the first URI; and
based on receiving an invalid response via the first URI, communicating with the application using the second URI.

2. The method of claim 1 , further comprising:
providing application services in relation to the first account based on communications with a first application server identified by the first URI.

3. The method of claim 1 , wherein the communicating with the application using the first URI comprises:
transmitting a request for a set of communication instructions to the application, the request being based on the first URI, wherein the receiving of the invalid response comprises receiving a server error message in response to the request for the set of communication instructions.

4. The method of claim 1 , wherein the communicating with the application using the first URI comprises:
transmitting a request to an application server to provide a service in relation to an established communication, the request being based on the first URI and being embedded with state information.

5. The method of claim 4 , wherein the receiving of the invalid response comprises detecting an error in the service being provided by the application server.

6. The method of claim 4 , wherein the communicating with the application using the second URI comprises:
transmitting a subsequent request to a second application server to provide the service in relation to the established communication, the subsequent request being based on the second URI and being embedded with updated state information.

7. A system comprising:
one or more computer processors; and
one or more computer-readable mediums storing instructions that, when executed by the one or more computer processors, cause the system to perform operations comprising:
receiving, via a settings interface, a first Uniform Resource Identifier (URI) associated with an application and a second URI associated with the application;
in response to receiving an incoming communication request directed to a first communication address associated with a first account, communicating with the application using the first URI; and
based on receiving an invalid response via the first URI, communicating with the application using the second URI.

8. The system of claim 7 , wherein the operations further comprise:
providing application services in relation to the first account based on communications with a first application server identified by the first URI.

9. The system of claim 7 , wherein the communicating with the application using the first URI comprises:
transmitting a request for a set of communication instructions to the application, the request being based on the first URI, wherein the receiving of the invalid response comprises receiving a server error message in response to the request for the set of communication instructions.

10. The system of claim 7 , wherein the communicating with the application using the first URI comprises:
transmitting a request to an application server to provide a service in relation to an established communication, the request being based on the first URI and being embedded with state information.

11. The system of claim 10 , wherein the receiving of the invalid response comprises detecting an error in the service being provided by the application server.

12. The system of claim 10 , wherein the communicating with the application using the second URI comprises:
transmitting a subsequent request to a second application server to provide the service in relation to the established communication, the subsequent request being based on the second URI and being embedded with updated state information.

13. A non-transitory computer-readable medium storing instructions that, when executed by one or more computer processors of one or more computing devices, cause the one or more computing devices to perform operations comprising:
receiving, via a settings interface, a first Uniform Resource Identifier (URI) associated with an application and a second URI associated with the application;
in response to receiving an incoming communication request directed to a first communication address associated with a first account, communicating with the application using the first URI; and
based on receiving an invalid response via the first URI, communicating with the application using the second URI.

14. The non-transitory computer-readable medium of claim 13 , wherein the operations further comprise:
providing application services in relation to the first account based on communications with a first application server identified by the first URI.

15. The non-transitory computer-readable medium of claim 13 , wherein the communicating with the application using the first URI comprises:
transmitting a request for a set of communication instructions to the application, the request being based on the first URI, wherein the receiving of the invalid response comprises receiving a server error message in response to the request for the set of communication instructions.

16. The non-transitory computer-readable medium of claim 13 , wherein the communicating with the application using the first URI comprises:
transmitting a request to an application server to provide a service in relation to an established communication, the request being based on the first URI and being embedded with state information.

17. The non-transitory computer-readable medium of claim 16 , wherein the receiving of the invalid response comprises detecting an error in the service being provided by the application server.

18. The non-transitory computer-readable medium of claim 13 , wherein the communicating with the application using the second URI comprises:
transmitting a subsequent request to a second application server to provide the service in relation to the established communication, the subsequent request being based on the second URI and being embedded with updated state information.
