Abstract:
1. A method, comprising: initiating an interactive voice response (IVR) session between a first endpoint and an IVR system over an IP network, wherein said initiating comprises issuing a first signaling protocol invite message from the first endpoint to the IVR system and establishing an initial media path between the first endpoint and the IVR system; issuing a second signaling protocol invite message from the IVR system to a second endpoint to establish a connection between the IVR system and the second endpoint; establishing a first media path between the first endpoint and the second endpoint; establishing a second media path between the first endpoint and the IVR system; and receiving at the IVR system a notice of a telephony event from the first endpoint, wherein said establishing the first media path and the second media path comprises issuing a third signaling protocol invite message from the IVR system to the first endpoint for the first endpoint to establish the first media path which is bidirectional between the first endpoint and the second endpoint and for the first endpoint to establish the second media path between the first endpoint and the IVR system.
