Would you mind telling me how to setup the GXP-2000's VLAN/QoS
settings with the DES-1226G? I just purchased the DES-1226G and want
to make sure I setup it up right. I don't have the ability to run
separate wiring for the PC and the phone and that's why I need this
help.
Thanks,
Daniel

I have heard good things about the D-Link DES-1226G switch ($150 at
newegg). If you can run a separate cable to the computer and
phone. If you can't run the extra cables, then configure your
phone to tag itself as part of the voip vlan and let the switch tag
everything else as the computer vlan.
I happen to have asterisk running as a router, so I use it doing
QoS with tc (traffic control) and wondershaper set to prioritize
based on port ranges. I sent a patch to the debian bug tracking
system a while back with a few improvements -- I should check on
that. It basically prioritizes smaller packets before larger
packets with ~8 levels of priority and groups of sizes for the
packets. Just doing that automatically handles 80% of the need for
prioritization without specifying port ranges for the sip rtp packets.

They are all connected to the same switch. It's a Netopia DSL
router/modem/switch for the BellSouth DSL service. The computers
are connected to the PC port behind the GXP-2000.
Any suggestions?
Thanks,

I don't think it is the phones...

Mike,
I added a qualify=500 on those phones. My client has peers
100218 thru 100222 (a total of 5 phones). Below is the messages
log since I activated it this morning at 8:30AM:

As you can see, it only happens to a couple of their phones and
at random times. They're behind a DSL circuit. I don't know if
it's because their DSL line is going up/down. They don't
necessarily claim their Internet goes down, however, they are
not constantly check it.
What would you (or anyone else) suggest?
Thanks,
Daniel

Do you have multiple phones going down at the same time? If
so, monitor them with "qualify=500" in sip.conf to see if they
hit that limit. If you see more than one go down within a
short period of time, you have network problems. Check the
quality of the network switches they have.
