4500G QoS Questions

I have two Voice VLANs. 192.168.1.0/21 & 10.0.0.0/24 (and a few other Data VLANs) on two 4500G switches with 10Gig Fiber as a backbone.

The 192 network (and data VLANs) have no problems with Packet Loss or Jitter, the 10 network seems to be having troubles. Both use the same switches and same backbone fiber/Ethernet.

I was hopping for someone to review my configs to double check I'm doing QoS properly. (End to End sniffs show DSCP values haven't been modified, but I'm getting different Jitter/Packet Loss Values.)

iperf - UDP Two Stream 64kbits/sec - 10 network
Code:
BANDWIDTH     JITTER     PACKET LOSS
58.8 Kbits/sec  21.029 ms    (0%)
58.8 Kbits/sec  15.907 ms    (0%)
58.8 Kbits/sec  11.676 ms    (0%)

iperf - UDP Two Stream 64kbits/sec - 192 network
Code:
BANDWIDTH     JITTER     PACKET LOSS
70.6 Kbits/sec  1.137 ms    (0%)
70.6 Kbits/sec  0.567 ms    (0%)
70.6 Kbits/sec  0.287 ms    (0%)

Wireshark (port mirror) - 10 Network
Code:
RTP DSCP Expedited Forwarding 0x2e - 19592Packets - 156 Lost (0.8%) - 0.63 Max Jitter (ms)

Wireshark (port mirror) - 192 Network

Shouldn't I be getting jitter for all VLANs?
 
Strange route or am i missing something?

ip route-static 0.0.0.0 0.0.0.0 192.168.1.255

Don't think QOS will solve it.

What AVAYA pbx do you have?

Oops. Typo. Don't worry the Default Route is correct and working. 192.168.1.254

I don't think the PBX version should have anything to do with Jitter...

NOTE: I've tried multiple PCs (10/100/1000 & 10/100), in different parts of the switch arraignment above, it seems jitter is consistent no matter which part - (if I'm on the 10 VLAN).
