I'm hoping someone might have some insight into the problem we're having. We have multiple sites connected with a VPN to our main site (hub/spoke). Everything works well with this connection except for VOIP and Video using Microsoft's OCS. Video conferencing experiences dropouts in the video.
looking at the OCS logs I think it might be an Untangle/VPN issue. We've tried setting up QOS rules in Untangle but it seems that by the time QOS sees the data it's already been processed into the VPN stream (thus and QOS rules applying to SIP aren't tiggered).
Any ideas as to how to identify the source of this issue and troubleshoot?
Thanks for your time and consideration.
