## 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.

## Claims

### Claim 1

A method for processing telephony sessions of a network including at least one application server and a call router, the method comprising 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.
