Cisco Cisco Unified IP Interactive Voice Response (IVR) 8.0(1) Leaflet

 describes the property of the Filter tab of the Get Digit String 

customizer window.

The Get Digit String customizer window closes, and the name of the triggering 
contact and the result digit string variable appear next to the Get Digit String step 
icon in the Design pane of the CRS Editor.

Use the Implicit Confirmation step to confirm an action without having to ask a 
question. This step is typically used in speech-enabled Solutions.

A prompt explaining the action to be taken is played back and the system waits a 
configured number of seconds for input from the caller. If the caller presses any 
DTMF digits or speaks anything before the configured timeout, the confirmation 
is considered to have failed, and an Explicit Confirmation step should be used. 

Input  Length

Variable indicating the maximum number of digits 
or characters. When this limit is reached, the step 
stops accumulating digits and returns.

Digits filter

Specifies the digits that you want to accept from 
the caller (excluding the terminating and cancel 
keys). If the caller enters digits that you do not 
choose, the system plays an error prompt for the 
caller and retries the Input step until the maximum 
numbers of retries is reached. At that time, the 
Unsuccessful output branch executes.

Terminating Digit

Variable indicating the key used to indicate the 
end of caller input (DTMF only). The terminating 
key overrides the Maximum Input Length to 
terminate input. 

Cancel Digit

Variable indicating the key the caller presses to 
start over.
