The finally responded to my emails regarding renewal price. The did make a nice offer, but not fully addressed the questions I had about why their website is down, support is almost non-existent, their affiliate program abruptly ending with partial payouts, and features (3-way calling) going away with no notice. They have been reliable for most of the 2 years... although in the past couple of months I have experienced some dropped calls. Somehow I just don't trust them.
The options I am considering are to port back into GV using SimonTel or continue with VL.
