Well, at least you answered my first question. ;)

You'll likely want something like:

class-map match-any SOMENAME
match ip dscp ef
match protocol sip
match (an ACL)

policy-map SOMENAME-PARENT
class class-default
shape average 5000000 !if shaper only counts L3, you'll want to shape 10 to 15% less
policy SOMENAME-CHILD

policy-map SOMENAME-CHILD
class SOMENAME
priority percent 40
class class-default
fair-queue

interface WAN
service-policy output SOMENAME-PARENT

What are the devices at each location?

Do your devices host the MPLS interface or hand-off "regular" Ethernet to a service provider's PE?

Have you asked your MPLS provider if they support any QoS?

This MPLS "link" is strictly p2p?

two location having Cisco 4331 router and static routing 

we need sample Qos configuration for VoIP SIP
