The GCACT_ADDMSK, GCACT_SUBMSK and GCACT_SETMSK parameter IDs can be 
assigned one of the following values (of type GC_VALUE_LONG), or an ORed combination of 
the values: 

GCMSK_ALERTING_STATE 

GCMSK_CALLROUTING_STATE (for E1, T1, and ISDN technologies only)

GCMSK_DETECTED_STATE 

GCMSK_GETMOREINFO_STATE (for E1, T1, and ISDN technologies only)

GCMSK_PROCEEDING_STATE 

GCMSK_SENDMOREINFO_STATE (for E1, T1, and ISDN technologies only)

See the Global Call API Library Reference for more information on the gc_SetConfigData( ) 
function.

Some call state transition events can be masked so that the events are not generated. Although an 
event may be masked, the corresponding call state transition can still take place. This configuration 
can be done by issuing the gc_SetConfigData( ) function with a target_type of 
GCTGT_GCLIB_CHAN and a target_ID of a line device, and passing the appropriate set ID and 
parm IDs. 

The set ID used in this context is GCSET_CALLEVENT_MSK and the relevant parm IDs are:

GCACT_ADDMSK

Enable the notification of events specified in the value in addition to previously enabled 
events.

GCACT_SUBMSK

Disable notification of the events specified in the value.

GCACT_SETMSK

Enable the notification of events specified in the value and disables notification of any event 
not specified.

The GCACT_ADDMSK, GCACT_SUBMSK and GCACT_SETMSK parm IDs can be assigned 
one of the following values (of type GC_VALUE_LONG), or an ORed combination of the values:

GCMSK_ALERTING

GCMSK_DETECTED

GCMSK_DIALING

GCMSK_PROCEEDING

GCMSK_REQMOREINFO (for E1, T1, and ISDN technologies only)

Using the gc_SetConfigData( ) function with a target_ID of a board device to mask events for all 
devices associated with a board is not supported. Call state events can be masked on a per line 
device basis only.
