Monitor Network in QOS environment

Hi All,

i am using L3 MPLS VPN services from a provider.

They are doing QOS, like my Voice, Data, ICMP. all traffic is classified in their network and take different paths.

Now sometime when we face voice issues, simple ICMP ping , TCP ping, will not give me insight if there are any packet losses, since Voice packets are taking someother path with in MPLS cloud due to DSCP marking of Voice pack to 46.

is there any tool in which i can change DSCP value of my packets and test out network response? or any monitoring tool that can do this by default?

i am looking for freeware at the moment or trial

Cisco's IP SLA feature set is designed for jsut this sort of thing. Depending on what platforms you are using, it may suit your needs.
