Hi, I have two PBXs in two different sites, exchanging communication by VoIP across a network link. I'd like to setup some QoS for phone traffic (good idea, isn't? :-)) but I'm not a "guru" of QoS. Some preliminary suggestion? Good reading? A simple setup? Do I need to setup QoS only between routers or along the whole chain of devices? Thanks in advance Mimmus P.S. Sorry for my bad english
