Outbound calls only - 1way choppy audio

Posts: 17 · Vonage Forum Associate Joined: Jan 21, 2006 Posts: 17

I am currently experiencing 1way choppy audio only when placing outbound calls. Inbound calls are 100% clear both directions. Has anybody else experienced this? What was the resolution?

I have exactly the same problem since 2 weeks or so...
Never had this problem at this point for the las 12 months.
Nobody give me a fair solution so far!
See: vonage-forum.com/ftopic12301.html" target="_blank">http://www.vonage-forum.com/ftopic12301.html

After many searches I could say that the problem is related to a QOS (quality of sound) issue.

So I found a broadband accelerator by D-Link. The DI-102 Broadband Internet/VoIP Accelerator uses an intelligent engine to detect and prioritize bandwidth-sensitive packets so that they can be sent over the Internet as soon as the request is made. This results in faster processing of real-time based packets, less latency, and a better user experience. This harware is plugged beetween the modem and the router and do not need any particular setup.

DI-102Can be found at http://www.tigerdirect.com for $70.

Hope this will help!

I understand QOS being an issue with the voice quality, but how can it selectively change, depending upon who made the phone call? The problem should show up, regardless.

That aside...I finally made contact with Vonage CS. They made some changes in the server at their end, and requested I power cycle the router. I will make some test calls after doing so and go from there.

Is your voice choppy or the other party's voice? I've had a similar issue with certain numbers. The other party's voice came in distorted, kinda like static modulated over their voice. It only happened when I called certain POTS numbers. I had a lengthy support/troubleshoot call with their tech support in Jersey. The rep pulled debug info from my device while I was calling the numbers that had issues and sent it off to the Engineers. I haven't heard back from anybody at Vonage, but so far the issue has been resolved. Funny thing is, he had me call his cell phone to see if the problem can be reproduced. I guess I can just call him directly now if the issue happens again Wink

My voice was choppy to the distant end, but their voice was clear to me. Again, this only happened on outbound calls. ALL inbound calls are flawless.

If you haven't tried re-booting your system, you should. Power up in the correct order- typically modem, wait, router (if any), wait, adapter and computers.

Power resets are a given whenever changes are made, I'll grant you that.

On an update note...I spoke at great length with an english-speaking New Englander technician last evening, and I succeeded in stumping him. In conducting several tests with him online, I was able to demonstrate the exact steps required to create the choppy audio, and those that net clear voice quality.

The bottom line? The choppy audio only occurred when I conducted the Vonage speed test residing inside of the vonage.com domain. I ran several FTP upload tests to other random domains, and no choppy audio was experienced. I have therefore concluded that this is a QOS issue at, or near the vonage.com network at play only when calls are originated from my end.

Far more investigations are required, but I'm thinking that if it proves to be a Vonage problem, enough complaints will eventually drive it away. I could be wrong, but.....

Inbound & outbound calls don't have to go through the same gateways/proxy servers @ Vonage, so this does actually make sense.

The problem seems to be restricted now to only when I conduct speed tests to Vonage. My outbound calls seem to remain clear, just as long as I restrict my speed tests to other servers across the US. Weird.....But as they say in the phone business, "Trouble's leaving here okay!" Wink
