If a board is not running in enhanced mode, use cdiStopTones to stop transmission of a tone to a station (started using cdiStartTones).
If the board is running in enhanced mode, the DSP automatically stops tone transmission at a station when the station is placed on-hook or a DTMF is detected. In this case, cdiStartTones returns CTAERR_FUNCTION_NOT_ACTIVE.
Refer to Transmitting tones for more information.
