Hello,

I have a Grandstream HT-386. My problem is with the bad voice quality.
My current configuration is:
HT-386 FXS Port1 is connecting to eu.voxalot.com.
I have a premium account in Voxalot which the service provider is Voipbuster.
Voipbuster declares the available codecs as:
G.711 (64 kbps)
G.726 (32 kbps)
G.729 (8 kbps)
G.723 (5.3 & 6.3 kbps)

HT-386 can support
G723.1, G.729A/B, PCMU, PCMA, iLBC, G.726-32 codecs.

From another post in the Voxalot Forums, it was adviced to set ulaw;alaw;g726;g729;ilbc;gsm codecs for the provider, which I did so.

Unfortunately, I couldn't manage to make it perform well and the voice is always choppy and most of the calls with an echo. Last week, after trying to use a Nokia I was amazed about the quality of the voice (where I set the built-in Internet Call).

Anybody achiving a good setup with HT-386, Voxalot and Voipbuster or Voipstunt or any Betamax services (preferably due I want to call U.S. for free).

Thanks in advance.
