You don't give hardware specifics, so that it may be that your softphone actually does mark the traffic as EF. I know on Cisco switches, traffic all gets marked as BE unless the port is set to trust the QoS marking. Cisco routers (not including layer-3 switches) will trust the markings coming in. I don't know how non-Cisco devices handle this. Could it be that the VoIP traffic is marked as EF, but the switch is marking is down as it comes in?

The idea is to mark it as close to the source as possible so that you can treat it differently for as long as possible. The real problem (that you can deal with) is where the traffic exits your network. You need to set up priority queues there so that VoIP can be served before the other traffic. You have no control over how it is treated after it leaves your site, but the exit is a choke point that you can do something about. | |
