asterisk users - Feb 2005 - Problem with the IAXy and Netgear Hubs!

Hi,

I'm having trouble when I try to contact any of my IAXy boxes connected
to a Netgear (DS516 and DS524) hub, but if I connect the IAXy box to
another hub or switch (not netgear) or directly to my Asterisk server
with a crossover cable it works just fine.

Do you have any idea of what can be causing this?

Thanks in advance,

Raul.
