-		IMPORTANT: Users of this function should make sure that the
-		dialog created is further processed statefully. Specifically, if a
-		stateless response is sent out after dlg_manage() is called, the
-		dialog cannot be handled properly. So make sure that a transaction
-		exists or create it explicitly using the tm module. This is a
-		shortcoming of the current implementation that may be resolved in a
-		future version hopefully.
