Question : Cisco QoS VoIP quality issues

We're having some issues with VoIP quality at many sites. We've tried ajusting out configurations but and it seems to have helped a little but we're still having quality issues (the remote site can't hear us or we can't hear them).

Any suggestions on what I can do to increase the quality?

This is our latest config:
[code]
!
class-map match-all VOICE
 match ip dscp ef
class-map match-any CALL-SETUP
 match ip dscp af31
 match ip dscp cs3
class-map match-any INTERNETWORK-CONTROL
 match ip dscp cs6
 match access-group name IKE
class-map match-all TRANSACTIONAL-DATA
 match ip dscp af21
!
!
policy-map LLQ-from-Branch
 class CALL-SETUP
  bandwidth percent 10
 class TRANSACTIONAL-DATA
  bandwidth percent 22
 class INTERNETWORK-CONTROL
  bandwidth percent 5
 class VOICE
  priority percent 25
 class class-default
  fair-queue
policy-map Shaper
 class class-default
  shape average 384000 3840 0
  service-policy LLQ-from-Branch
!

[/code]

This was our original config:
[code]
!
class-map match-all VOICE
 match ip dscp ef
class-map match-any CALL-SETUP
 match ip dscp af31
 match ip dscp cs3
class-map match-any INTERNETWORK-CONTROL
 match ip dscp cs6
 match access-group name IKE
class-map match-all TRANSACTIONAL-DATA
 match ip dscp af21

 class VOICE
  priority 256
 class class-default

policy-map Shaper

Answer : Cisco QoS VoIP quality issues

Those speeds are pretty slow, probably not going to be able to support to many voice calls with any amount of data going over them.  No amount of traffic shaping will overcome link saturation.  Are you monitoring throughput on the cable connections as you test your calls?
