[Connectivity] Comcast Router Latency

Click for full size
Background - Our company has Comcast for web and a T1 for VoIP. We are having some local calls going directly to voice-mail which is caused by the network not responding fast enough. I contacted our T1 provider and after a few emails I see the bottleneck is often 96.120.37.49 on PingPlotter and other tracert tools that I have run the past two days. That IP does not show any DNS information but is in the route.

Our T1 network provider starts at 63.209.147.150 and when I opened a ticket with them said the problem is before that IP address.

I have uploaded a screen shot from PingPlotter.

I'm trying to understand why you're showing a traceroute which appears to be via your Comcast connection for an issue you're having with VoIP which you said should be going over your T1.

Do you suspect the VoIP is improperly going over Comcast instead of the T1?

For simplicity: I am testing for latency on Comcast to our T1 provider.

It would be more informative to show a trace FROM the T1 to some other hosts (especially the VoIP provider's servers).

From what I can tell of the ping plotter graph, it looks like you're seeing packet loss/issues with the Comcast connection.

Is 63.209.147.150 your T1 IP?

That pingplotter shows no issues.

You reach your provider in a avg of 22ms with no packet loss.

Yeah, I misread the column for jitter thinking it was packet loss. There's some jitter, but that's not unusual on a cable network.
