If ATDX_CPTERM( ) returns CR_ERROR, you can use ATDX_CPERROR( ) to determine the Call Analysis error that occurred.

#define	Error Description
CR_MEMERR	Out of memory trying to create temporary SIT tone templates (exceeds maximum number of templates).
CR_TMOUTON	Time-out waiting for an SIT tone.
CR_TMOUTOFF	SIT tone too long (exceeds a ca_mxtimefrq parameter).
CR_UNEXPTN	Unexpected SIT tone (the sequence of detected tones did not correspond to the SIT sequence).
CR_MXFRQERR	Invalid ca_mxtimefrq field in DX_CAP. If the ca_mxtimefrq parameter for each SIT tone is non-zero, it must have a value greater than or equal to the ca_timefrq parameter for the same SIT tone.
