Dialogic Corporation

The gc_GetCTInfo( ) function can be used to retrieve product information (via the CT_DEVINFO 
structure) for the media sub-device (ipm) attached to the network device (ipt). If no media device is 
associated with the network device, the function returns as though not supported. 

The gc_GetResourceH( ) function can be used to retrieve the media device (ipm device) handle, 
which is required by GCAMS functions, such as, gc_SetAlarmParm( ) and gc_GetAlarmParm( ) 
to set and retrieve QoS threshold values. The function parameter values in this context are: 

linedev 

the network device, that is, the Dialogic

®

 Global Call API line device retrieved by the 

gc_OpenEx( ) function

resourcehp 

the address where the media device handle is stored when the function completes 

resourcetype 

GC_MEDIADEVICE 

Applications must include the gcipmlib.h header file before Dialogic

®

 Global Call API can be 

used to set or retrieve QoS threshold values. 

The other resource types including GC_NETWORKDEVICE (for a network device), 
GC_VOICEDEVICE (for a voice device), and GC_NET_GCLINEDEVICE (to retrieve the 
Dialogic

®

 Global Call API line device handle when the media handle is known) are also supported. 

The GC_VOICEDEVICE option above applies only if the voice device was opened with the line 
device or opened separately and subsequently attached to the line device. 

The gc_GetXmitSlot( ) function can be used to get the transmit time slot information for an IP 
Media device. The function parameter values in this context are: 

linedev 

The Dialogic

®

 Global Call API line device handle for an IP device (that is, the handle returned 

by gc_OpenEx( ) for a device with :N_iptBxTy in the devicename parameter and a media 
device attached). 

sctsinfop 

A pointer to the transmit time slot information for the IP Media device (a pointer to a CT Bus 
time slot information structure). 

This function is only available if the call transfer supplementary service was enabled via the 
sup_serv_mask field in the IP_VIRTBOARD structure when the board device was started.
