We have CS1000S at the main office, full voip, CS1000B's at branch offices and symposium 5. Branches are connected to the main office via MPLS network with QoS and calls travel from the main office where Symposium resides to the branches over virtual trunks.
We get intermittent complaints from users at the branches that incoming symposium calls are garbled, the volume goes up and down and sometimes they can't hear the first 5-10 seconds of the call. We've done troubleshooting to try and isolate the problem, patched up media cards, swapped out media cards at the branches. The problem is that it's pretty hard to replicate and it only happens to a few specific people.
I'm starting to think it might be a QoS issue but I don't handle QoS on our MPLS network and the guy who does run it, says it's working correctly. We are looking into getting PVQN/Vivinet but at $100 per phone/device to monitor, that's a little steep. Is there anything else we should be doing to try and isolate the problem?
