Stops the DTMF detector.

DWORD adiStopDTMFDetector ( CTAHD ctahd )

ctahd CTA context handle returned by ctaCreateContext.

• SUCCESS
• CTAERR_FUNCTION_NOT_ACTIVE
• CTAERR_INVALID_CTAHD
• CTAERR_INVALID_SEQUENCE
• CTAERR_INVALID_STATE

• ADIEVN_DTMF_DETECT_DONE
  Once the detector has stopped, the ADI service generates a DONE event with the value field set to CTA_REASON_STOPPED.

This function disables detection of DTMFs. Detection is generally enabled automatically by the call control protocols upon transition to the ADI_CC_STATE_CONNECTED state. After this function is called, DTMF events will not be reported. The detector may be restarted with adiStartDTMFDetector. The DTMF detector cannot be restarted until the DONE event is received.

Note: The digit collection function, adiCollectDigits, will not work if you disable DTMF detection. No digits will be collected and no events will be generated.
