Try making your classes and ACLs more detailed.
class-map match-all voip_traffic
match access-group 100
class-map match-all voip_control
match access-group 101
policy-map llq_256_voice_3calls
class voip_traffic
priority 134
class voip_control
bandwidth 8
class class-default
fair-queue
access-list 100 permit ip any any precedence critical
access-list 100 permit udp any any range 16384 32767
access-list 100 permit ip any any dscp ef
access-list 100 permit udp any range 16384 32767 any
access-list 101 permit tcp any range 2000 2002 any
access-list 101 permit tcp any any range 2000 2002
access-list 101 permit tcp any range 11000 11999 any
access-list 101 permit tcp any any range 11000 11999
access-list 101 permit tcp any any eq 1720
access-list 101 permit tcp any eq 1720 any
