8. IP-Specific Event Cause Codes

The event cause codes described in this chapter are defined in the gcip_defs.h header file.

When a GCEV_DISCONNECTED event is received, use the gc_ResultInfo( ) function to retrieve the reason or cause of that event.

Table 29 lists the supported IP-specific event cause codes and provides a description of each code. When using gc_DropCall( ), only event cause codes prefixed by IPEC_H2250 or IPEC_Q931 should be specified in the cause parameter. See Section 3.1.5, "gc_DropCall( )" for more information.
