Revision History Document No. Publication Date Description of Revisions 05-1816-006 (continued) Function Summary by Category chapter : Added new section for Call Modification Functions. Updated Global Call Function Support by Technology table to show additional functions supported on DM3 and IP. (Also updated the individual function reference pages that were affected.) For DM3 E1/T1, gc_SetConfigData( ) is supported. For DM3 Analog, gc_CompleteTransfer( ), gc_SetupTransfer( ), and gc_SwapHold( ) are supported on Dialogic® DMV160LP Combined Media Board only. For IP, gc_AcceptInitXfer( ), gc_AcceptXfer( ), gc_InitXfer( ), gc_InvokeXfer( ), gc_RejectInitXfer( ), and gc_RejectXfer( ) are supported. Function Information chapter : Added the following function reference pages: gc_AcceptModifyCall( ) gc_RejectModifyCall( ) gc_ReqModifyCall( ) gc_SetAuthenticationInfo( ) gc_util_copy_parm_blk( ) gc_util_find_parm_ex( ) gc_util_insert_parm_ref_ex( ) gc_util_next_parm_ex( ) gc_AttachResource( ) function reference : Added note following the caution about calling dx_initcallp( ). gc_CCLibNameToID( ) function reference : Added “GC_H3R_LIB” (IP call control library) to the list of call control library names. gc_DropCall( ) function reference : Added caution about GCEV_DROPCALL event with CAS protocols (PTR 34237). gc_Extension( ) function reference : Added caution about how to identify the extension function across technologies. gc_GetCallInfo( ) function reference : In Table 6, added IP_CALLID info_id parameter. In Table 6, deleted restriction that CATEGORY_DIGIT is supported on Springware only; it is now supported on DM3 as well. gc_GetLinedevState( ) function reference : Corrected two printf statements in the example (PTR 32616). gc_GetResourceH( ) function reference : Added caution about GC_NETWORKDEVICE resource type not supported with Springware analog (PTR 34286). gc_Listen( ) and gc_UnListen( ) function reference : Added caution about the sharing of time slot (SOT) algorithm. gc_MakeCall( ) function reference : Added caution about multiple calls to gc_MakeCall( ) in synchronous mode (PTR 33852). gc_Start( ) function reference : Added caution that the network adapter must be enabled before calling the function when using Global Call over IP, and added information about how to start with the network adapter disabled. gc_util_delete_parm_blk( ), gc_util_find_parm( ), and gc_util_next_parm( ) function reference : Corrected the Errors section (PTR 32544). Events chapter : Added a second entry for the GCEV_CONNECTED event. Data Structures chapter : Added GC_PARM_DATA_EXT data structure reference page. 12 Dialogic ® Global Call API Library Reference — January 2008 Dialogic Corporation
Document No. Publication Date Description of Revisions 05-1816-006 (continued) Revision History CCLIB_START_STRUCT and GC_CCLIB_STATE data structure reference : Added “GC_H3R_LIB” (IP call control library) to the list of call control library names. GCLIB_MAKECALL_BLK data structure reference : Corrected typo in the Description section; changed GCMAKECALLBLK_DEFAULT to GCMKCALLBLK_DEFAULT. Error Codes chapter : Made minor change to description of GCRV_CCLIBSPECIFIC. 05-1816-005 November 2003 Function Summary by Category chapter : Updated Global Call Function Support by Technology table to show additional functions supported on DM3 and IP. (Also updated the individual function reference pages that were affected.) For DM3 E1/T1, gc_CompleteTransfer( ), gc_Extension( ), gc_HoldCall( ), gc_RetrieveCall( ), gc_SetupTransfer( ), and gc_SwapHold( ) are supported. For DM3 ISDN, gc_HoldAck( ), gc_HoldCall( ), gc_HoldRej( ), gc_RetrieveAck( ), gc_RetrieveCall( ), gc_RetrieveRej( ), and gc_SetConfigData( ) are supported. For DM3 Analog, gc_BlindTransfer( ) is supported. For IP host-based stack, gc_GetCTInfo( ) is supported. Made other miscellaneous corrections to the table. gc_GetCTInfo( ) function reference : Revised description to indicate that the CT_DEVINFO structure is defined in ctinfo.h. gc_LoadDxParm( ) function reference : Changed extension for the voice channel parameter file from .vcp to .dxp (PTR 30887). gc_MakeCall( ) function reference : Revised description about terminating a call in asynchronous mode (PTR 30985). gc_SetChanState( ) function reference : Added a caution to not call gc_SetChanState( ) while gc_ResetLineDev( ) is active. gc_SetInfoElem( ) function reference : Revised note about using gc_SetUserInfo( ) instead of gc_SetInfoElem( ). gc_SwapHold( ) function reference : Revised description of callonhold parameter. CT_DEVINFO data structure reference : Provided more detailed field descriptions. DX_CAP data structure reference : Provided more detailed field descriptions. 05-1816-004 September 2003 Function Summary by Category chapter : Added Supplementary Service Functions section. Updated Global Call Function Support by Technology table to add the supplementary service functions. Function Information chapter : Added the following function reference pages: gc_AcceptInitXfer( ) gc_AcceptXfer( ) gc_InitXfer( ) gc_InvokeXfer( ) gc_RejectInitXfer( ) gc_RejectXfer( ) Events chapter : Added events for the supplementary service functions.
