I received my Grandstream adapter (wow is it small!).
I have been testing the service and so far all seems well.
I particularly liked the self-provisioning part of the adapter.

True plug and play, It was ready for use within a few minutes (may have been less) that I plugged it in.

What is the purpose of the Green Button (the one that indicates connectivity and VM waiting), since it seems to be "clickable". Pushing on it seemed to do nothing except making a clicking sound.
