Abstract:
1. A method of exchanging data between first and second telephony terminals during a telephony call, comprising the steps of: (a) initiating said call between said terminals using the Session Initiation Protocol (SIP); (b) said first terminal generating information to be exchanged, wherein said information is generated in a format in which each item of information is defined as resources, referenced using uniform resource indicators (URIs); and (c) said information being transmitted from said first terminal to said second terminal as a message using SIP; wherein said first telephony terminal is a telephony interface of an automated telephony application and said second telephony terminal is a telephony interface of a user in communication with said automated telephony application; wherein said information to be exchanged describes a process of said automated telephony application comprising a model of a workflow or of a menu structure available to a user of said second telephony terminal during said call and the method further comprising the steps of: (d) providing a representation of said model to said user of said second terminal; (e) receiving from said user an input indicating an interaction with said model; (f) generating from said input an instruction to said first terminal, wherein said instruction is generated in a format in which said input is defined as resources referenced using uniform resource indicators (URIs); and (g) transmitting said instruction from said second terminal to said first terminal as a message using SIP; whereby said user of said second terminal can interact with and control said telephony application according to said instruction.
