To send a nonstandard Facility message, use the gc_Extension( ) function in asynchronous mode 
with an ext_id (extension ID) of IPEXTID_SENDMSG. The target_type should be 
GCTGT_GCLIB_CRN and the target_id should be the actual CRN. The GC_PARM_BLK must 
contain parameter elements that identify the message type, the nonstandard data, and the 
nonstandard data identifier. At the sending end, reception of a GCEV_EXTENSIONCMPLT event 
indicates that the message has been sent.

The parameter element that identifies the message type is: 

IPSET_MSG_Q931 

IPPARM_MSGTYPE

value = IP_MSGTYPE_Q931_FACILITY 

The parameter element for the Nonstandard Data data is:

IPSET_NONSTANDARDDATA

IPPARM_NONSTANDARDDATA_DATA

value = Nonstandard Data string, max length = max_parm_data_size (configurable at 
library start-up)

The parameter element for the Nonstandard Data identifier is one (and only one) of the following:

IPSET_NONSTANDARDDATA

IPPARM_NONSTANDARDDATA_OBJID

value = array of unsigned integers, max length = MAX_NS_PARM_OBJID_LENGTH 

IPSET_NONSTANDARDDATA

IPPARM_H221NONSTANDARD

value = IP_H221NONSTANDARD structure

When the Dialogic

®

 Global Call API library receives a nonstandard Facility message, it generates a 

GCEV_EXTENSION event with the ext_id value IPEXTID_RECEIVEMSG. The extevtdatap 
field in the METAEVENT structure for the GCEV_EXTENSION event is a pointer to an
