Why would you want to give 90% of a serial link to voice and 10% to
data, that is weird from my own view. That's about 1389.6kbps for voice
and 46kbps for each customer's data traffic .... (Assuming the serial
interface is 1544kbps)

There are so many ways to achieve this, this is one of them ...

!
class-map match-any VOICE
 match dscp ef
 match dscp af31
 match protocol rtp audio
class-map match-all CLIENT1
 match access-group name CLIENT1
 match not dscp ef
 match not dscp af31
 match not protocol rtp audio
class-map match-all CLIENT2
 match access-group name CLIENT2
 match not dscp ef
 match not dscp af31
 match not protocol rtp audio
class-map match-all CLIENT3
 match access-group name CLIENT3
 match not dscp ef
 match not dscp af31
 match not protocol rtp audio
!
policy-map PRIORITY
 class VOICE
  priority percent 90
 class CLIENT1
  bandwidth percent 3
 class CLIENT2
  bandwidth percent 3
 class CLIENT3
  bandwidth percent 3
!
Int s0/0/0
 max-reserved-bandwidth 100
!

Then configure ip extended access-lists CLIENT1, CLIENT2 and CLIENT3 to
respectively match any traffic destined for your individual clients

Many Thanks

I don't understand.
In my point of view, use PQ for voice traffic only, then exclude voice
traffic fron ACL 101 102 103 and use a normal service policy without
hierarchical MQC like this:
   service policy qos
     class voip
      priority 90 ! Because max-reservable you set is 90%
     class client1
      bwd 33
     class client1
      bwd 33
     class client1
      bwd 33

Also, note that in your configuration below, you applied the qos only to
voice traffic and no qos is garanted for class-default!

Subject: qos problem

I have the following scenerio that I need some help . I have a link on
a serial interface that passes voice and data traffic to three clients.
My qos requirement is to give strict priority to all voice traffic
regardless to which client it is destined. I then have to give each
client one third of
any bandwidth that is still available. The following is my proposed
configuration.

class-map match-all rtptraffic

 match protocol rtp voice

class-map match-all client1

 match access-group 101

class-map match-all client2

 match access-group 102

class-map match-all client3

 match access-group 103

policy-map othertraffic

 class client1

  bandwidth percent 33

class client2

  bandwidth percent 33

class client3

  bandwidth percent 33

policy-map voice

 class rtptraffic

  priority percent 100

  service-policy othertraffic

interface serial 1/0

max-reserved-bandwidth 90

service-policy output voice
