Thanks PCTech, I ended up answering my own question about the payment methods... I ended up editting my previous post before you posted.
One feature that I see that Packet8 offers that I cannot find on Vonage's website is
Anonymous Call Blocking. This is something I currently have that I really like. I hate when I do not know who is calling me. I am not sure if this is available with Vonage. But I do like Vonage's Bandwidth saver feature....
