VoIP + 3650 PoE = Echo + Dropped Calls...etc

Troubleshooting a setup involving three 3650 48 port 10/100 PoE
switches with GBit uplinks to each other. PC linked off the Polycom
phones which are linked off the switches. Goes like this:

Switch --> Phone --> PC (daisychain style)

PBX is locally hosted.

Call quality is poor when paging internally and when receiving calls
from the provider over a dedicated T1 link. It looks as if the person
that configured these switches made each port a trunk port so that the
phones and computers can transmit over the shared wire. Makes sense.
I'm not sure of the QoS settings however because it doesn't appear that
there are any. I'm looking for some advice on what QoS would be in
this scenario and how to implement that on the switchports. Any
tech-doc references would be helpful as well. I'm having trouble
finding a concise document from Cisco that explains leading practices
for this. We have ~70 users and phones in this layout. Network tests
also show that we are consistently experiencing 5% packet loss to the
phones when we do a "mini-stress test" PCs are working fine and
experience no problems. Here is the config:

I wouldn't expect Qos is the problem, bear in mind Qos will only really
take affect when the network is congested. You mention the quality is
poor even internally, things won't be congested in a gb environment.

None of your switch ports are nailed down to the phones, they're all
auto negotiatiating. Nail down the switch ports to 100/full, and check
on the phone as well, assuming cisco phones, go into network
configuration, and its something like option 39 or 40 to nail the phone
port speed down to 100/full down to the switch, and you can do the same
up to the pc.

Thats my first thought.

I have a great doc on qos, but not sure where, I'll see if i can dig it
out.
