I have developed an online web application to reserve seats using Netbeans. Now I need to add the feature where in when the user calls a particular phone number listed, he would be able to book the seat through phone by entering information like date, seat,etc and making the selection by using the keypad of the phone.
So far I am thinking of using VoiceXML with Tellme voice gateway. I wanted to know if this is the right direction or is there any other technology to implement this feature.
