Cautions
Some IEs may require a Call Reference Value (CRV) to be part of the contents.
The Call Reference, in this case, must be the Call Reference value assigned by the
network, not the Call Reference Number (CRN) that is assigned by Dialogic and
retrieved using the cc_GetCRN( ) function. It is up to the application to correctly
format and order the IEs. Refer to the ISDN Recommendation Q.931 or the switch
specification of the application's ISDN protocol for the relevant CCITT format.
See the Example code for details.
