Comcast vonage dispute

The NetworkHealth link for my area (651) shows they did maintenance this morning. However, the problems I experienced occured well after the maintenance was complete.

Well, between the one-way audio and the Vonage site outage, I'm thinking the root of the problem lies with Vonage. I could be wrong. But the one-way audio problem is just too wide spread to be any specific ISP's fault.

Now I'm getting very choppy audio, but a speed test checks out okay.

How about a www.testyourvoip.com test? What is your score on that test, both "to you" and "from you"??

I'm having Comcast troubles also! I'm in the 847 area code. I'm a very new customer as of yesterday (2/9/06). I hooked up everything last night and all was right with the world. This morning all outgoing audio was choppy. Incoming audio was great. I also have not been able to get to vonage.com. Something strange is afoot. Here's what is also strange. If I initiate the call, outbound audio is choppy. If I receive a call, outbound audio is fine.

Here's some details.

1. Chicago Suburbs (847)
2. Comcast
3. 864 kbs up/ 8 Mbs down
5. RT300
6. Modem---->Vonage Adapter (isolated for testing)
7. outgoing choppy audio
8. voiptest details:

Sorry, don't have the proper signature and didn't want to post a million details, but I'm having the same problem right now.

I'm not a new subscriber, but I live in Deerfield and have had Comcast/Vonage for over a year at this location. I have had my share of Comcast issues in the past, but those seem to have been resolved.

The problem today is totally new. We cannot make any calls now because no one can hear what we are saying... nor can I access www.vonage.com . Don't know what's going on... I was going to try and call Vonage first...

anyone know the IP of the next hop from our Vonage boxes? I'd like to do ping test/tracert to that ip to see roundtrip latency. It would be good because with a tool like Ping Plotter you can see where the latency builds through the trace.

So if any Vonage admins are out there, what IP can i trace to?

Thanks,

Todd

The SIP server is sip.vonage.net - but the actual server you will use to make your calls depends on the call. Inbound, it'll be the nearest Vonage site to you. Outbound, it'll probably be the nearest Voange site to the person you are calling.

So far, the testyourvoip.com results posted have been pretty bad. 3.8 is ok, but will be marginal. 2.6 with a near 5% packet discard - get out the dixie cups, duct tape, and string!

Since testyourvoip has nothing to do with Vonage, bad results on both the testyourvoip test and bad performance on Vonage points (IMHO) directly at the Internet connection.

Makes me kinda fear my cable company's impending buyout by Comcast. Suscom has been rock solid since I moved here in August, absolutely zero downtime and near zero problems of any kind.
