Our WAN routers mark certain application traffic (eg. premium 2 class - with a predetermined DSCP/TOS byte). The PE routers are supposed to preserve and transport our DSCP markings thro' the cloud. But when these pakets reach the other PE site, these packets are remarked as best-effort (standard class). There may be an issue with your PE router configs (related to TOS byte - MPLS EXP bit mapping within your network).
There are different kinda service flavors being offered and i m not sure in which category your customer falls into.
In general there are 2 types of service being offered by SP which is basically called as managed and unmanaged.
In managed services the SP will honour the customer markings and carry the markings throughout the SP cloud and deliver it at the other end.
But in case of unmanaged services SP resets the markings and carry it on their own markings.
First you need to find out whether they fall into any kinda service category.If not do check out your PE end config which is applied onto the ingress interface where the customer link is getting terminated.
Also you can ask about the supportings like the mechanism they are using to verify/check the same at their end to make sure the claim made by the customer is rite.
