Description
It configures the duration time (in milliseconds) for each digit when a sequence of
DTMF tones is played out automatically.
Note: If the time interval between two DTMF digits is less than this value, two or more
same DTMF digits could be identified as one DTMF digit. This may cause the loss of
one or more DTMF digits. For example, 2662 may be identified as 262. If so, you can
modify the value of this parameter to a little lower than the default value.
