What happened:
we receive InserSubscriberDataRequest fromHLR and we see onInsertSubscriberDataRequest method print out Got ISD; but when using dialog.send(), we do out see any outgoing mesage.
Here is the method:
@OverRide
public void onInsertSubscriberDataRequest(InsertSubscriberDataRequest arg0) {
System.out.println("got ISD");
try {
MAPDialogMobility diag = arg0.getMAPDialog();
diag.addInsertSubscriberDataResponse(arg0.getInvokeId(), null, null, null, null, null, null, null, null, null);
diag.send();
} catch (MAPException e1) {
e1.printStackTrace();
}
}

What you expected to happen:
Expecting sending TC-CONTINUE

it can be SCCP routing is not correct
If you have the log, you may see some error related to SCCP

[naseemr]

If it is routing error, would the UpdateLocation message be sent in first place? I dot see any error log from my exception.
