Appendix A: SS7-Specific Error Codes

When a function fails, the gc_ErrorInfo( ) function, or the gc_ErrorValue( ) function (deprecated), can be used to retrieve error code information as follows:

• When the gc_ErrorInfo( ) function is used, the a_Infop parameter is a pointer to a GC_INFO structure that contains both the standard Global Call error or result value (gcValue field), and an SS7-specific error or result value (ccValue field).
• When the gc_ErrorValue( ) function is used, function parameters point to a standard Global Call error or result value (gc_errorp function parameter), and an SS7-specific error code (cclib_errorp function parameter).

Table 13 lists SS7-specific error codes and describes the meaning of each code. These error codes are defined in the [Dialogic installation directory]\inc\cc_s7.h header file.
