Hi All, I have been looking at my policy-map stats on my ciscos between my Main site and my trouble site. here is my policy:

My policy is as follows:
class-map match-any VoIP
match ip dscp ef
match ip dscp af41

policy-map voipQos
class VoIP
priority 768
class class-default
fair-queue
random-detect dscp-based

Inteface serial0
service-policy output voipQos

Here is what I see:

Main Site:
