Rant: I Hate Vonage

Have I mentioned that I hate Vonage? After all of those witty ads and promising benefits, I was suckered into signing up. I even ported our main line over. How much do I dislike thee...let me count the ways:
1) after 6-8 minutes, calls are often dropped. Really great when you are on hold with Vonage tech support for 30 minutes to work on why your calls keep dropping. You lose that call and have to go back to the queue.
2) it drops callers half-way through voice mail messages so they have to call back twice
3) it takes 1-2 seconds for the Phone Adapter to hook up the IP to the POTS network when people call in. You answer and say "Hello", but because the connection was not made, your caller doesn't hear you. You have to say Hello multiple times.
4) call waiting from hell. Instead of discretely beeping once or twice, it beeps loudly every 4 seconds until the voice mail picks up. You have to stop talking until Big Ben is done chiming.
5) occasional echo
6) it goes down when our Internet goes down...this has been happening recently as we are having DSL modem issues
7) my wife is extremely displeased with all of this and wants to go back to SBC. However, getting Vonage to give up our number will be quite an ordeal...it is a number hostage.

Am I alone here or does VoIP really stink? Other experiences?
