I'm thinking to move my test server (the one on receiving side) from<br>
Xen VM to a physical ARM machine at <a href="https://www.scaleway.com/" target="_blank">https://www.scaleway.com/</a> in<br>
France. It would record audio and raw UDP packets and provide them for<br>
downloading to everyone.<br>
<br>
Do we know about any timing issues on ARM platform?<br>
<br>
if someone sponsors some additional DID numbers, that will be appreciated.<br>
