QoS for voice calls in L2L

Hi,

End user has a L2L from main office to one branch  at 10 MBps. Link is used mainly for data traffic but also voice calls are sent through this link.

When data traffic is high voice call quality are really bad.

Any of you has a template I can set for this L2L in order to warranty a good voice quality for at least 8 voice calls using g729r8 codec.

I tried to set the following config but some commands were not accepted.

MAIN OFFICE - WITH WS-C3750G-24TS     12.2(44)SE2           C3750-ADVIPSERVICESK9-M

access-list 110 permit ip any any precedence critical
access-list 110 permit ip any any dscp ef
access-list 110 permit udp any any range 16384 32767
access-list 110 remark ToS VoIP media stream classification
access-list 111 permit ip any any precedence flash
access-list 111 permit ip any any dscp af31
access-list 111 permit tcp any any eq 1720
access-list 111 permit tcp any any eq 1719
access-list 111 permit tcp any any eq 2428
access-list 111 permit tcp any any range 2000 2002
access-list 111 permit tcp any any range 8001 8002

class-map match-any VoIP-Traffic-LAN
match access-group 111
match access-group 110
class-map match-all VoIP-Traffic
match ip dscp ef

policy-map QoS-Policy-L2L
class VoIP-Traffic
