Stops the out-of-band signaling bit detector.

DWORD adiStopSignalDetector ( CTAHD ctahd )

ctahd CTA context handle returned by ctaCreateContext.

• SUCCESS
• CTAERR_FUNCTION_NOT_ACTIVE
• CTAERR_INVALID_CTAHD
• CTAERR_INVALID_SEQUENCE
• CTAERR_INVALID_STATE

• ADIEVN_SIGNAL_DETECT_DONE
  Once the detector is stopped, the ADI service generates a DONE event with a value field of CTA_REASON_STOPPED.

This function disables detection of the transitions of incoming signaling bits. After this function is called, incoming out-of-band bit transitions will not be reported.

Note: This function is mutually exclusive from standard call control. CTA contexts running a standard protocol are usually excluded from use of this function.
