Jaap,
Well, I installed xTen eyeBeam (a softphone) on my PC and voila! My problem
is that the Polycom and LinkSys phones are doing something I don't
understand yet. The eyeBeam is sending/receiving RTP and I can follow it no
problem. Sorry for being a newbie and bothering the group with this and
thanks for responding.

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,
