Set Question Box Play/Response Option

$flushdtmf

This command causes a $play_var operation, or the playing of the image voice description, to proceed even if unprocessed DTMF input from the caller exists prior to the message being played. Such DTMF data will be discarded.  However DTMF input arriving during the message play will still stop the message, unless $nointerrupt is used.

This command has no parameters

Default: description will be suppressed if unprocessed DTMF input exists

Example:

$flushdtmf
