Rise Time Criteria
              
Defines how the Rise Time criteria should be configured for
DTMF detection.
              
  * CheckSr: Enable the Step Rise criteria and disable the
    Confirm DTMF SNR criteria.
  * ConfirmSnr: Enable the Confirm DTMF SNR criteria and
    disable the Step Rise criteria.
              
The Step Rise criteria compares the current frame energy to
the high frequency power of the previous frame. If the
current frame energy is high enough, then it passes the test,
further validating the DTMF.
              
Disabling the Step Rise criteria may result in deteriorated
talk-off performance, but increases the detection of
malformed DTMF.
              
The Confirm DTMF SNR criteria is an additional
Signal-to-noise ratio test performed before a confirmed DTMF
report is sent to finally validate the DTMF.
