How to ensure input is only from keypad?

[nrv2008]

We have an application where the grammar mode is set to DTMF, the property "bargein" to TRUE, because we need to allow the caller to key-in his/her response even before the IVR instructions are completed. Specially if they already familiar with the steps.

But whenever the system is specifying instructions and it is interrupted by a voice or a conversation or background noise nearby, the system responds with an invalid input statement. It seems to take audio noise as a user input even if is is in DTMF. We need to setup the system to ignore the voices or noises unless there is a specific keypad entry.

Below are the settings:
Grammar Mode = DTMF
Barge In = TRUE
Sensitivity = 0
Type = DIGITS

Hi,

To ensure that the input is DTMF-only (entry only by phone keypad), you could use the following <property>:

Code: Select all

<property name="inputmodes" value="dtmf"/>

By setting this properly globally in your IVR application, you will ensure that the only input that can be entered is through phone keypad only.
