Cisco QOS - IOS sample configuration for Cisco VoIP

I am looking for some sample IOS QOS configurations, particularly a real world example anyone might be using.  In particular I am trying to apply QOS to Cisco VOIP and Citrix.  I have followed some of the documentation on Cisco's website for marking and CBWFQ but I am not sure if this is the best way to accomplish this.  An example with a Fast Ethernet and Serial Interface would be most helpful.  I am very familar with IOS CLI and your help is greatly appreciated.

When the serial interface is has full load on it do you drops in the class-default queue when you do a show policy-map interface.  This is where I am confused.  I have the exact same configuration, priority queuing only, on an interface but other traffiic still seem to monopolize the circuit?  I see matches in the queue but even at full load the class-default queue is not showing drops.

The only way I can seem to ge this to work they way I want is to police the class-default queue but I am trying to avoid this as I would like to script the configuration to multiple routers.
I'm using callmanager and it does admission control, so we have a bandwidth cap for voice calls on each remote site.  Callmanager does some magic in the background with routers, so I don't know if it is imposing some bandwidth policing when admission control is enabled, but I've not seen the problem you describe.

i have below configuration which i m planning to configure but it throws some error when i configure
class class-default
  fair-queue
it shows there is no class map defined for class default please help,

class-map match-any voice-traffic
match  dscp ef
class-map match-any voice-signal
match  dscp af31
!
policy-map voice-policy
class voice-traffic
  priority 200
class voice-signal
  bandwidth 8
class class-default
  fair-queue
!
policy-map shaper
class class-default
  shape average 350000 3500 0
  service-policy voice-policy
!
interface FastEthernet4
service-policy output shaper
your last line,

"service-policy output shaper" needs to be

"service-policy output voice-policy"

voice-policy is the name of the policy map thus it needs to be reflected exactly in your service-policy output command.

scratch that i just saw your 2 policy maps, let me look at ours and compare.  I dont think we have 2 policy maps in our config.
Can you get the exact output for me, we have 2 QOS maps.  One for VPNs and MPLSs, this looks like the shape one we use for VPN's but i dont see where the problem would be.

Let me know exactly what and where you are typing then the error it throws.
