A remake of the Envox Studio application.
The Envox Studio is a cool application because it is highly scriptable... or should I say: easily scriptable. What give Envox a slight competitive advantage over other IVR vendors are its cool 4GL scripting environment.
Each phone line can be scripted. A script is a sequence of actions that is executed for each line. A typical script example could be: Wait for a phone call, look up phone number in database, present voice menu if caller is known, if caller presses 1 on the phone then send an e-mail to support account, hang up and go back to waiting for new call
Of course you dont want to build huge scripts/applications in this language, but listing the feature set of the Envox Studio, you cant help to get excited.
