See the Global Call API Library Reference for more information about the gc_ResultInfo( ) 
function. 

When an option that enables call analysis is selected, a GCEV_MEDIADETECTED event can be 
received. The gc_GetCallInfo( ) function can be used to determine the type of detection (by setting 
the info_id function parameter to CONNECT_TYPE). The valuep function parameter indicates 
the connect type when the function completes. Typical values in this context are: 

GCCT_FAX 

Fax detection 

GCCT_PVD 

Positive voice detection (PVD) 

GCCT_PAMD 

Positive answering machine detection (PAMD) 

See the Global Call API Library Reference for more information about the gc_GetCallInfo( ) 
function. 

Certain call analysis attributes can be configured on a per call basis using the gc_MakeCall( ) 
function with an associated GC_PARM_BLK (accessible via the GC_MAKECALL_BLK and 
GCLIB_MAKECALL_BLK structures) that contains the CCSET_CALLANALYSIS parameter 
set ID and one of the following parameter IDs: 

CCPARM_CA_PAMDSPDVAL 

Positive answering machine detection (PAMD) speed value. Quick or full evaluation of 
answering machine detection. Possible values are: 

PAMD_FULL – Full evaluation of response. 

PAMD_QUICK – Quick look at connection characteristics. 

PAMD_ACCU – Recommended setting. Does the most accurate evaluation detecting live 
voice as accurately as PAMD_FULL, but is more accurate than PAMD_FULL (although 
slightly slower) in detecting an answering machine. Use PAMD_ACCU when accuracy is 
more important than speed. This is the default value. 

CCPARM_CA_NOANSR 

No Answer. The length of time (in 10 ms units) to wait after the first ringback before deciding 
that the call is not answered. Possible values are in the range 0 to 65535. The default value is 
3000. 

CCPARM_CA_NOSIG 

Continuous No Signal. The maximum amount of silence (in 10 ms units) allowed immediately 
after cadence detection begins. If exceeded, a no ringback is returned. Possible values are in 
the range 0 to 65535. The default value is 4000. 

CCPARM_CA_PAMDFAILURE 

PAMD Fail Time. The maximum time (in 10 ms units) to wait for positive answering machine 
detection (PAMD) or positive voice detection (PVD) after a cadence break. Possible values are 
in the range 0 to 65535. The default value is 800.
