The Help Digit is a digit that is defined for each LineGroup control. If the Help digit is detected on any channel belonging to the LineGroup, normal voice processing will terminate and the call will exit out of HelpDigit node in the LineGroup control.
Use the Help Digit to implement the system wide options, such as "Press 0 at any time to transfer to the operator".
The Help Digit connection can be overridden on a control by control basis using the Connections Page, or it can be disabled in the GetDigits control using the DisableHelp property.
NOTE: The Help Digit function is not active at all times throughout a call. Instead, it applies only to processing of the user input, which occurs in certain states of certain controls (like the GetDigit control, waiting for digits). You may think of the Help Digit as an extra option being automatically added by the system to every DTMF menu in your call-flow.
Operation of Help Digit is affected by other VBVoice properties related to normal processing of the user keystrokes:
|
Terminate on digit property |
Controls whether the Help Digit (or any other digit) may barge into a playing prompt. If not set, the prompt will play to completion, even if the Help Digit is pressed. |
|
Disable global help digit property |
Allows you to turn the Help Digit on or off per control. |
|
Clear digits on entry property |
Discards any user input waiting in the buffer to be processed, including any Help Digits. EXAMPLE Consider a scenario when a Help Digit is pressed while in a Delay control (which has no user input processing ). The digit is simply stored in a buffer and causes no immediate action. The call is then passed to a GetDigit control (which does process user input). If the GetDigit controls has the Clear digits on entry ON, the Help Digit will be permanently lost and no action will take place. |
