we have an integrated voice and data circuit and lately we've been having voice issues. Every so often the provider has to bounce the iad because of memory utilization and bandwidth utilization. I've installed mrtg on one of my server and am monitoring the outside interface of our firewall since I don't have access to their Cisco IAD/Router. I do see the bandwidth spikes; however i haven't been able to pinpoint the source of the congestion yet...except that it is coming from outside the network.
When I talk to my provider, they are not much help, telling me that their Cisco router is in bridge mode and just passing the traffic to our network and thus they can't really see the traffic because it's in bridge mode.
Shouldn't they at least be able to see what's hitting their network even if their router is in bridge mode?
