Guy,
Thankyou very much indeed for taking the time to point me to that info - I
was well aware of the problems that could be caused by switches or switching
hubs, but I wasn't familiar with the problems caused by 10/100Mbps
auto-sensing hubs. This was my problem and now that I have my ethereal box
configured in 10Mbps mode it is seeing the VoIP traffic just fine.
Thanks again,
Mat
