gc_Listen( ) Variances for IP
The gc_Listen( ) function is supported in both synchronous and asynchronous modes. The 
function is blocking in synchronous mode. 
Note:
For line devices that comprise media (ipm) and voice (dxxx) devices, routing is only done on the 
media devices. Routing of the voice devices must be done using the Voice API (dx_ functions). 
8.3.17
gc_MakeCall( ) Variances for IP
This function is only supported in asynchronous mode. 
The Dialogic
®
 Global Call API supports multiple IP protocols on a single IPT Network device. See 
, on page 48 for more information. When using a multi-
protocol network device (that is, one opened in P_IP mode), the application specifies the protocol 
in the associated GC_MAKECALL_BLK structure, using the set ID IPSET_PROTOCOL, the 
parameter ID IPPARM_PROTOCOL_BITMASK, and one of the following values:
IP_PROTOCOL_SIP 
IP_PROTOCOL_H323
