I also have Vonics and they've been a horribly unreliable voip service. I thought after my bad experience with SunRocket going under, that I wouldn't have trouble again. Unfortunately, I signed up with Vonics for their annual service. For the last few months, I had mostly incoming phone service. Today (10/08/08), I have a dial tone, but no incoming or outgoing service. When I call my number from another phone, I get the message "the phone you are trying to reach is out of service."
This is bad because I was in the middle of porting my number to Callcentric, and they told me this will prevent them from doing so. Since Vonics' website is gone, their phone numbers dead, no email replys - WHAT CAN I DO? Vonics was bad news... is bad news! I hope I don't lose my number because of them. They deserve to go bankrupt for what they did to their customers.
