[OpenSIPS-Users] dlg_val before create_dialog

[Bogdan-Andrei Iancu]

That means some other script function created the dialog in advance. you 
can find which one by adding something like this on top of your request 
route:
     script_trace( 1, "$rm from $si, dlg is $DLG_status", "dbg");

And see where the print changes from NULL to 1 ;)
