*** I am a noob ***


I am having a problem getting good call quality with any VOIP provider. I jsut changed to Vitality and it is terrible quality. Did a heap of debugging and Vitality cannot find the cause of the poor quality.

In addition to my server I have a hosted server and the call quality with the hosted werver is crap as well. So presumable the problem is not with Vicidial. I thought maybe it was the soft phone that was causing the problem. I am using Twinkle in Ubuntu. Well I changed to eyebeam in Windows and the sound quality is identical.

There have been times with one carrier when the quality was good - once for a whole day - so maybe the problem is just bad luck with carriers.

I have to get good call quality carrier and need to be connected ASAP. I only need 10 channels. And recommendations for a carrier (preforably one I can sign up with on line right away so I can test)

Thanks - Chris

p.s. 100% grateful for Vicidial

sound card is often the culprit, as can be the headset/microphone unit. consider getting at least one actual sip phone so you can test that as well. and remember that it may not necessarily be the "carrier", but it could be your connection path to the carrier. so other carriers (with other paths) may work better.

try a carrier with multiple voice servers across the nation (so they can find one geographically closer to you for connecting voice).

And try a nice windows box with an HD sound card and a decent mic/headset as a test to see if it's just the agent workstations causing your issue.

Thanks for the reply. I am getting bad echo on around 50% of my calls but it varies. The echo is on the customer end but it sounds fine on my end. I have the same result with operating systems, different softphones, and even when I call from a hosted server the result is the same.

Could a bad sound card cause echo on the customer end only?

Also, I was under the impression that the sound card in the head set replaced the sound card i the computer. Is this correct?

Thanks

yep

headsets do not have sound cards. the sound card on the computer is essential. better quality headsets can capture sound better and transmit sound better, but cannot interpret the digital signal which is what the sound card is for. in this case, the microphone could be catching sound from the ear piece or they could just be cheap, bad wires could cause crossover, cheap sound cards could cause poor interpretation of the signal and bad drivers could cause all sorts of problems.

so try it on a box that does not share these issues to find out.

FYI I did testing as you suggested and it seems to be jitter that is the problem.
