Fixed Length Digits

Before release 6.4.1, the gateway can collect a sequence of digits that is ended with a pond # key.

But for digits that length is know, such as an account number or social security number, it is much easier for a caller just to enter the digits without the pond key.

To specify that in your VXML file, use the following:

<dtmf>$digit:3</dtmf>

If you use IVR Studio, specify the length in the element property page:
