Setting Up CPN Fields in the GC_PARM_BLK Data
Structure
Before calling the gc_MakeCall( ) function, you must set up the CPN fields to be included
in the GC_PARM_BLK data structure. The GC_PARM_BLK should include the existing
parameter set ID IPSET_CALLINFO and the newly defined parameter IDs described in
the New Parameter IDs section, which specifies which CPN fields are to be set in the
parameter block structure of a Make Call block.
To set up the CPN fields in the GC_PARM_BLK structure, call the
gc_util_insert_parm_ref( ) function.
Code Example
The following is an example of how to specify the CPN fields for sending.

/* Set CPN fields in the Make Call Block to be sent out via SETUP message */
cgpn_ton = 0x1;

cgpn_si = 0x0;
cgpn_pi = 0x0;
// Note that the field values must be valid.
