Messageflow is SS7 -> USSD GW -> SIP (ProcessUnstructuredSSRequest)
The probable reason is in the code ParentSbb.java:
(https://github.com/RestComm/ussdgateway/blob/master/core/slee/sbbs/src/main/java/org/mobicents/ussdgateway/slee/ParentSbb.java)
public void onProcessUnstructuredSSRequest(ProcessUnstructuredSSRequest evt, ActivityContextInterface aci) {
// ..............
ChildRelation relation = this.getSipSbb();
ChildSbbLocalObject child = (ChildSbbLocalObject) relation.create();
child.setCallFact(call);
child.setXmlMAPDialog(this.getDialog());
forwardEvent(child, aci);
"child.setCallFact(call);" code sets "call" into a CMP variable of a child SBB.
"forwardEvent(child, aci);" schuld then initiate of "onProcessUnstructuredSSRequest()" event in the child SBB.
But inside child SBB this CMD is null. We need to investigate it.
