well, it does say SIMPLEX in the fxp0 flags section. I don't honestly know if this means it's negotiated half duplex, or something beyond that.... 10baseT is capable of running full duplex, although this requires a NIC capable of is, as well as a switch that can do FD. And regarding the 1% comment, the benefit with full duplex comes in to play with collisions, not so much traffic amounts.

Why do you think it is running simplex. I read the above and see where it says "(100baseTX full-duplex)" I don't think 10BaseT can run full duplex. I could be wrong but I don't think so. But why does it matter? A single VOIP connection will not even use 1% of a simplex 10BaseT.
