Interactive Voice Response (IVR)

Interactive Voice Response (IVR).

Interactive Voice Response (IVR) is the technology that let you interact with a menu using a touch-tone telephone. In our day to day life we have already come across IVR in many ways, a best example is when you call banks

It is very easy to set-up such a menu with Asterisk.

The following is just an example for an IVR system where you call the number 9877777777 and you enter the IVR system. First you will get the greeting message ("welcome to dash dash Bank, please press 1 for Account related Enquiry, 2 for Credit card Enquiry or press 9 to talk to pur representative") and during this message you can press key 1, 2 or 9. According to the number pressed, you will be directed to the right extension
