Question : Problem: QOS for voice traffic

OK I had a question posted similar to this before and I thought I had what I needed but maybe not.  So here is what I have:
Site1
1 -  3560
1 - 4507R
1 - 3845
 
Site2
1 -  3560
1 - 2811

At Site 1 the 3560 port Gi 0/1 plugs into the 4507R on Gi 7/46.  The 3845 router Gi 0/0 plugs into the 4507R on port Gi 3/1.  Site two is basically the same the 3560 port Fa 0/48 plugs into the 2811 on port Gi 0/1.
Now at both sites I'll have IP phones plugged into the 3560's.  On the ports where I will have the IP phones plugged in I've done the following:
auto qos voip trust
mls qos trust device cisco-phone (these phones are nortel but I was told this would probably work fine)

Now at site 1 on port Gi 0/1 of the 3560, ports Gi 7/46 and Gi 3/1 of the 4507R i've done the following.
auto qos voip trust

Now on the routers at each side I have the following:
class-map match-all control
 match access-group 151
class-map match-all voice
 match access-group 150
!
!
policy-map voip
 class voice
  priority 1024
 class control
  bandwidth 50
 class class-default
  fair-queue
  random-detect dscp-based
And then on the serial interface I have:
service policy output voip

Now as i troubleshoot:
Show policy-map voice - looks fine
show policy-map interface serial 1/0 - I see that everything appears to be falling into the class default.  Nothing is showing under the voip.  

Is there a way to troubleshoot on each device to make sure things are getting marked properly and or what am i missing here.

Answer : Problem: QOS for voice traffic

According to documentation the CoS bits exist inside Ehernet frames only when 802.1Q trunking used.
dscp doesn't make sense for L2 networks and exist only in L3 headers.
