The only engineering you can do is at the cpe, where your traffic goes out and comes in. Thais makes that you at best can configure QOS at the BOTTLENECK, that may be your remote office router. If not applicable, than the agregation point (HQ) will be the next best. I still would say that you carefully analyse the traffic patterns and look at the bottlenecks. That is the no 1 point to do business.
