4.2.3. Setting the Values of Call Parameters

There are two ways to set the values of call parameters:

• Using the gc_SetUserInfo( ) function
• Using the gc_MakeCall( ) function

Using gc_SetUserInfo( ) to Set Call Parameter Values

Use the gc_SetUserInfo( ) function to set information element values for a single incoming call. At the end of the call, the values set as default values for the specified line device override these values. This is useful since the gc_AnswerCall( ) function does not have a parameter to specify a GC_PARM_BLK.

If a gc_MakeCall( ) function is issued after the gc_SetUserInfo( ), the values specified in the gc_MakeCall( ) function override the values specified by the gc_SetUserInfo( ) function.

See Section 3.1.18, "gc_SetUserInfo( )" for more information about the values of function parameters to set in this context.

Using gc_MakeCall( ) to Set Call Parameter Values

Use the gc_MakeCall( ) function to set the values of parameters for a call. The values set are only valid for the duration of the current call. At the end of the call, the values set as default values for the specified line device override the values specified by the gc_MakeCall( ) function.

See Section 3.1.14, "gc_MakeCall( )" for more information about the values of function parameters to set in this context.
