Possible values

0 through 8 units


5 units (100 ms)


Specifies how much is erased at the end of a recorded voice segment to remove any noise that was caused when the key that signals the end of recording was pressed. For example, when you record a message or a voice segment, and press * to signal that you have completed, * might introduce noise into the message or voice segment. Blueworx Voice Response then “rewinds” for the amount of time specified by this parameter so that the noise is not part of the voice segment and the next recording automatically erases it.

This value is adjustable in units of 20 ms. The default value sets this parameter to 100 ms.
