It's more than highly likely you have some other problem like jitter or a bad network connection.<br>Not many people would be able to tell the difference between the sound of an 8k PCM file and the same file encoded to G711 just by listening to it unless there was a severe problem somewhere. Since you are behind NAT you are even more likely to experience drops etc.<br>
<br>Record your files as 8k raw 16 bit PCM to get the best out of the file playback in FS and look elsewhere for your audio issues.<br><br>You can always make sure you are using the latest build of FS to rule out any temporary issues in the code.<br>

Using "playback" application, I'm playing a mu-law audio. I'm also starting the "vmd" application, so that I can replay the message on beep.<br>
