MPLS WAN Bandwidth issue

[cirdecus]

Our company currently has a facility in Mexico that runs their production lines. It includes:

12 Office users, using terminal services, Outlook and VoIP phones (just 2 phones) The Office users also connect to shared drivers and user drives.

15 Production machines running terminal services.

We currently have a 512Kbps MPLS WAN connection at that location and are experiencing a ton of latency and timeouts when the users attempt to download and send/receive email over the WAN through our exchange server, as well as terminal services slow downs and VoIP dropped and static calls.

The VoIP was fix by enabling QoS, but the other problems remain.

How much bandwidth should i need at that location and what else could be causing these problems?

I've run a PRTG scanner and grapher on the traffic and haven't found any other traffic that is taking up the bandwidth. I've check the interfaces on the router and have found them maxxed much of the time.

Is 512Kbps enough>?

Note: Storage is centralized at our corporate office and all shared resources are accessed through the WAN. The exchange server is also at our corporate office (off-site of the mexico facility) and they also access this through the WAN. Same with VoIP and terminal services

If you can provide screenshots of it during busy traffic time then I might be able to see if there's any issue.
