Re: [Equipment] Sudden call quality issues with Vonage
I tried it and here are the results. I'd appreciate any insight. (sorry so wordy, I"m trying to provide a complete picture). I am afraid I am not really doing so well at interpreting them. It would seem that the discards at 3.1 percent is too high ( I know the network team would be going ballistic if this were on the WAN at work  ), but I am far from an expert in VOIP.
When I ran the voip traceroute, the total route was around 67 ms, and 17 hops. The longest hops were 33ms between LA and Dallas (hop 5 to hop 6) , and then 21 ms from Dallas to Nashville (hop 6 to hop 7). There was 4 ms from Nashville to Atlanta (hops 7-17), and there was 8 ms from the host to the backbone in LA (hops 1-5). A regular traceroute and ping from my system to the remote host show similar latency between 70-100ms, and taking 23 hops.
Here are the stats from the test.
From me to San Jose:
Round-Trip
