This sample allows a caller to retrieve
information only after a correct password is entered. It also show
how to utilize variable to control the call flow.
The call flow
consists of one Digits Element, one Go-to
Element, and two Prompt Elements. A digits element
(Enter Password Element in the call flow) sets the system
ready to accept caller touch tone input, which must be ended
with a pound (#) key. A go-to element (Try Again Element) can
jump to any other element in the call flow diagram. A Prompt
Element plays the prompts defined in the element property.
You can open this design by selecting Library >
Password Protected Info from the program main menu.
A variable is used to hold dynamic
information. In this example, variable n represents the
number of attempts a caller has made.
To define a new variable, select the root
element (Incoming Call), then click on the Properties button
on the toolbar (Or select Edit > Properties... from the
program main menu), choose the Variable tab. Click the
New... button.
If you are new to IVR Studio, you can use
the buttons to build a value expression. In this example, you
enter n as the name and 1 as the value
expression. For values other than number, such as a street
name, please enclose the string with single quotes, such as
'123 Main Street'. Without the single quotes, it will be
treated as a variable.
After a caller entered the password
(Enter Password Element), the system checks the input. If the
input is "123", then the caller has entered the correct
password and it is transitioned to element Protected Info,
where a secret message will be played to the caller. If the
password entered is wrong, and the caller has made less then 3
attempts (n < 3), then it is transitioned to the Try Again
Element.
The value of variable n is
changed in the Try Again Element. Here, n is set to n + 1,
which represents one more attempt for password. To set new
value for a variable, select the element property sheet,
select the Action tab, then click the New... button.
If the caller has made more than 3
attempts on password, the system transitions to the Hang up
element, where it simply disconnect the call.
The transition is defined in the element
property sheet under the General tab.
To deploy the
application, select Deploy > Submit to Gateway... from
the program main menu. If the menu item is grayed out, select
Validate... first.
If you have multiple IVR application deployed, please see
IVR select application for more information.
Once deployed, restart the gateway to have the
changes to take effect.
You can use this sample as part of your IVR
application where you need to have password protected info.
