3.1.16. gc_SetConfigData( )

The gc_SetConfigData( ) function enables the setting of coder information for all devices on a board. The new coder settings apply only to devices that will be opened in the future, and do not override the coder settings of devices that are already open. The coder settings can be overridden by specifying coder information in the gc_SetUserInfo( ) function (device level) or the gc_MakeCall( ) function (call level).

Note: Coder information must be specified for a device before making a call (gc_MakeCall( )) or answering a call (gc_AnswerCall( )) on that device.

When using the gc_SetConfigData( ) function for this purpose, use the following function parameter values:

• target_type - GCTGT_PROTOCOL_SYSTEM
• target_id - The H.323 protocol ID. Since the protocol is dynamically assigned by Global Call, the gc_QueryConfigData( ) function must be used to obtain the correct protocol ID value. When using the gc_QueryConfigData( ) function, use the following parameter values:
  • target_type - GCTGT_GCLIB_SYSTEM
  • target_id - 0
  • source_datap - H323_NTSC (the protocol name)
  • query_id - GCQUERY_PROTOCOL_NAME_TO_ID
  • response_datap - A pointer to the protocol ID.
• target_datap - A pointer to a GC_PARM_BLKP structure that contains the parameters to be configured. Table 3 describes the set ID and parameter ID values that can be used in this context.
