gc_AttachResource( ) — attach a voice or media resource to a line device Parameter Description resourcetype type of resource. Possible values are: Termination Events GCEV_ATTACH indicates successful completion of the gc_AttachResource( ) function. GCEV_ATTACH_FAIL indicates that the gc_AttachResource( ) function failed.For more information, see the appropriate Global Call Technology Guide. Cautions GC_VOICEDEVICE GC_MEDIADEVICE mode set to EV_ASYNC for asynchronous execution or to EV_SYNC for synchronous execution Dialogic ® DM3 voice resources may only be attached to Dialogic ® DM3 network resources; that is, they cannot be attached to Dialogic ® Springware devices. Similarly, Dialogic ® Springware resources cannot be attached to Dialogic ® DM3 devices. A single media resource, a single voice resource, or both a voice and media resource may be attached to a Global Call line device at any given time. The call control libraries process and consume voice or media events of interest to the call control library before they reach the application. The gc_AttachResource( ) function does not perform time slot routing functions. The routing must be done during system configuration or performed by the application using the voice and network routing functions. Alternatively, the gc_OpenEx( ) function may be used to open, attach and route both the voice or media and the network resources. If this function is invoked for an unsupported technology, the function fails. The error value EGC_UNSUPPORTED is returned when the gc_ErrorInfo( ) function is used to retrieve the error code. If a protocol uses Global Tone Detection (GTD) tones for call analysis (assuming that GTD has not been disabled using the gc_SetParm( ) function), all pre-existing tone definitions for that voice resource are deleted. If the application requires additional tones after the initial set of tones are loaded, they must be redefined after calling the gc_AttachResource( ) function. The tone IDs cannot be in the range from 101-189. For protocols using GTD in any application that calls the gc_AttachResource( ) function several times on the same device (for example, when using resource sharing), the overhead associated with redundant tone deletion and definition may be avoided by calling the gc_SetParm(ldev, GCPR_LOADTONES, GCPV_DISABLE) function after the first call to the gc_AttachResource( ) function. Afterward, the application must reverse the effect of the gc_SetParm( ) function by issuing a gc_SetParm(ldev, GCPR_LOADTONES, GCPV_ENABLE) function when the call is complete. When using call progress analysis, the dx_initcallp( ) function must be called after calling the gc_AttachResource( ) function. The dx_initcallp( ) function initializes and activates Perfect Call call analysis on the channel and also adds all tones used in call analysis to the channel’s GTD templates. Calling dx_initcallp( ) before calling gc_AttachResource( ) results in the 64 Dialogic ® Global Call API Library Reference — January 2008 Dialogic Corporation
attach a voice or media resource to a line device — gc_AttachResource( ) deletion of all tones and the possible disabling of Perfect Call call analysis by the latter function. Note: The above caution is not applicable to E1/T1 technologies using ICAPI or PDK protocols with Global Call call progress analysis enabled by the application (in which case, the application would not be calling dx_initcallp( ) anyway).
