Jaap,
Yes, it is a LinkSys NH1005. I believe it is indeed a hub as I can see
traffic between HUD on my PC and my asterisk box. I see multicast packets
from a LinkSys phone (obviously) and, if I do not filter, I see a bunch of
stuff between my PC, the two phones and everywhere else hence my previaously
stated belief ;)
I see no SIP or RTP packets and am lost as to why.

Hi,
Are you ABSOLUTELY sure it's a hub? Many are switches underneath.
Check out the Wireshark Wiki on suspicious hubs.
Thanx,
