Hi
When we ring over voip from here to Germany the line is often noisy or the person on the other side can hardly hear us.
If we then hang up and they call from overseas the line seems to be good.
What can be the cause of this?
Below you see the settings.

Thanks

Unfortunately that is impossible to read clearly.

Who is your VoIP provider? There call routing is most probably the cause of the issues, and calls inbound from Germany are more than likely using different routing and interconnects which would be why the quality is better.

My apology, here the link to the picture.

You could try changing the codec order and trying alaw or ulaw as the default codec rather than ilbc. If you have no issues with call quality elsewhere the only solution would be to contact 2talk as it's probably an issue with an upstream provider.

oops let me write again :
first thing : change the codec . A good one with a low consume is g729. if after it the problem still persists contact 2talk , once there is a problem with their route . Anyway I can say 2talk is good for national calls but terrible for overseas calls . A good one for a reasonable price is pennytel. They charge 8 cents per call and not per minute

Morning
Thanks for the suggestions!
I will try what I can do and will post how I got on with it.
By the way; how would I join PennyTel with voip? Not as a soft phone, as a standard phone with local number?
Have a nice day!

I definitely disagree with your comment that 2Talk is terrible for overseas calls,  90% of my VOIP calls (both outbound & inbound) are overseas calls, mostly to landlines.

My codec order of priority is:

G711 uLaw
G711 aLaw
G729
G723
then various G726 (16, 24,32, 40)

My system is not a straight VOIP phone.
The Grandstream Handytone does not give the option of G711 and on 2talk support pages it says to use the iLBC and the the G729A/B.
So I'll have another go.

The Grandstream phone supports ulaw, this is known as PCMU (ulaw) and PCMA (alaw).

I'd be 99.9% positive a codec change won't fix anything and that the issue lies with an upstream transit provider, have you actually contacted 2talk and lodged a support ticket?

Hi sbiddle
Thanks for that.
Your comment supports what I have tried without success. I did try a couple/three of the codecs over a period of time and there has not been a satisfactory solution yet.
I'll try 2talk ticket system, as before it was too dificult to get an answer from them.
