PostPosted: Tue Jan 09, 2007 1:41 am    Post subject: choppy voice-what could cause high packet loss? Reply with quote Back to top

I just ordered Vonage, received the adapter today and tried a number of calls. Voice was very choppy and generally unintelligible. Cell calls indicated both parties heard about the same...less that 30% of syllables could be heard. I ran the speed test here a couple times and tried to run testyourvoip.com (w/ and w/o adapter connected), but that test failed on both Mac and XP.

The speed test here indicated very high packet loss 75%>x>55% each time, though all other measurements seemed good. I couldn't find others who've indicated the same problem. Any suggestion as to the cause?

Thank you very much for your help.

Nate,

Try plugging your handset directly into the Vonage device. This gives the best voice quality.
Recommended configuration
Of course, make sure to plug handset and router into the proper positions in the Vonage device. Remember to reboot *everything* after making any changes or experiencing any problems.

When you use <most> routers, voice traffic does not get priority over your PC traffic. Coming and going, your Voip gets chopped and shuffled with regular web traffic.

If you are using an old analog handset, you may have better voice with a digital handset. If your phone has a tone/pulse switch, try the other setting.

Be sure to come back and advise as to the solution, if you can.

Pepperoni,

Thanks for your suggestions. Unfortunately, still having the same choppy problems.

I did have a new digital handset plugged directly into the correct position of the dlinkVTA. I can't put the VTA in front of the router because it has no capability for this configuration, but it is plugged into the correct position of the (new) Belkin router as suggested in the VTA documentation.

When I was making the choppy calls, the router was not serving any computers. After retesting with Voip speed tests, the packet loss is always ~65% despite good speeds and QoS. I never have any trouble with internet traffic or downloading or uploading big files. I tried line quality and ping tests at broadbandreport.com, which reported 0% packet loss with similar speeds to the Voip speed tests. I'm comfused...why would Voip tests show large packet loss, but not other data transfers?

Thanks again,
Nate

I don't know. Perhaps you just don't notice on file downloads. Voip is a serial deal. A missed pack mucks everything following. On a file download, the wait for repeat isn't so evident.

Is it possible that your antivirus or hardware firewall is examining everything incoming with heuristics? That *could* be a drag.

What kind of speed do you show here:
McAfee speed test
It is measured with a dual file download.
Mine either pegs at 500 (usually) or 1000. (e.g. 5 minutes ago)

Frankly, I run softphone, so I'm not the best on diagnostics on the regular Vonmodem problems. I don't get these problems, even running wireless telephones, or softphone over wifi. I still think the proper setup is a plain old telephone plugged directly into the Vonage device, as recommended.

I think you've diagnosed the fault, but we don't know *WHY*, yet. That loss is just not acceptable, obviously.

The gurus will be cruising through eventually, we need better wetware to flog the problem. Someone will get you right before long, don't wander off too far.

I think I just figured out that it must be something with the Belkin Pre-N router, even though both laptops we use were shut down when I was having the problems.

I plugged the dlink vta directly into the modem and cycled power with the router completely out of the loop and shut down. When I picked up the phone and dialed, the voice quality was perfect. It is a new and pretty expensive router which has been great for wireless internet, maybe there is something I can do to tweak it.

Thanks

Belkin routers, especially the newer models have what's know as an SPI or Stateful Packet Inspection firewall. This will take every packet and examine it at the router. In cases where packet transmission latency is very important, eg. Voip, this can cause packets to take more than the 120ms that Vonage's devices buffer for to arrive. This will cause many packets to be discarded at the telephone adapter as it is arriving too late to be a valid part of the audio stream. This can, and will cause your audio to be extremely choppy. I believe your tests already show that your internet connection is not the issue here, as Modem -> TA had good two way audio, so I would bank on the issue being the SPI firewall. In this case I would normally recommend putting the Vonage adapter infront of the device with the SPI firewall you cannot do that with the VTA. Your best option here is to log into the Belkin and completely disable the SPI firewall. This may make your network less secure but for most residential applications NAT alone should be enough to protect your network and you can have this router work with your Vonage adapter.

Concur.

I have a router with SPI (Netgear WGT624) and the voice is better like this:

Cable > SB5120 > VT1005 > WGT624

Than like this:

Cable > SB5120 > WGT624 > VT1005

Thanks all,

After I saw that the pre-N router was the problem, I found hundreds of threads all over the web reporting the same problem. Shutting down the firewall and rebooting did the trick alright. Great sound quality now. I guess I could also get another cheap router to connect to the VTA in front of the belkin pre-n and leave the firewall up.

Belkin advertises this router as great for Voip, but then can't make it work without knocking out the firewall.

Firewalls are a sham. If someone really wants to get in, they will. My suggestion, save your money.

Packet sniffers in the hands of the right techs can get your Mac address to bypass your mac filtering, can decode your WEP encryption, and can fool NAT/PAT on the router.

If you're really worried about something like that, the easiest thing to do really is to change your private routed address, the "default" 192.168.2.1 address you have from your belkin to something else.

There's a ton of private IP's you can route on - check wikipedia - apples, for example use 10.x.x.x rather than 192.168.x.x.....

another good security step would be to change the UN/PW on your router, too. Wink
