I have been with Vonage for 2 years and Sun Rocket for 9 months. Recently I signed up with Packet 8. There website is pretty bad. If you change any features eg call forwarding or caller ID, nothing happens. Email notification does not carry voice mail. Some of the numbers can not be dialed with Packet 8. If you complain there is no response or no action. I am surprised that they are still in business.
