This is ifconfig on openbsd box: fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
I think this output shows that the fxp0 interface is on simplex mode.
The voice degradation I referred was by using xlite soft phone. I open 2 line similtaneously and dial to FWD and back to my incoming extension. Xlite is runnning on a w2k box with realtek 100M nic in auto mode. I can bearly hear the welcome message.
