Application and Session Variables

For Standard Application Variables, application.lastresult$ holds information about the last recognition to occur within this application. It is an array of elements where each element, application.lastresult$[i], represents a possible result. The number of application.lastresult$ elements will always be greater than or equal to one and less than or equal to 5.

For Session Variables, there are three variables that allow you to use the caller's phone number, the phone number the caller dialed, and a unique ID for the session.
