[Asterisk-Users] Terrible audio quality using Asterisk and X-Lite?

[WipeOut .]

Is the sound "choppy"??

If it is you are using the GSM codec... disable it and use G.711 (ulaw or alaw) and the quality should be fine.. the reason is that MS GSM is not the same as Linux GSM.. At least thats what I have been told..

Later..
