asterisk users - Jan 2004 - re: hardware requirement asterisk

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.

Yes its in simplex mode, but this parameter is NOT related to half/full
duplex on the port.

Check this output from my FreeBSD box:
%ifconfig -a
sis0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 10.1.1.254 netmask 0xffffff00 broadcast 10.1.1.255
        inet6 fe80::202:e3ff:fe23:e028%sis0 prefixlen 64 scopeid 0x1
        ether 00:02:e3:23:e0:28
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active

Its the media line you should check!

The SIMPLEX in flags is wheter the interface hears its own transmissions
or not.

In many years of doing professional network performance assessments, you
found the problem Houston. Statically define all interfaces (including
the switch, hope you're not useing a hub) to 10/100 full, and at least
part of the problem, if not all, will disappear. :)
