Vonage Telephone Service ?

[bigdog]

Do any Forum memebers use 'Vonage' telephone service ?

I believe this service uses ISP connection. If that is trues, do you notice any
Internet service bandwith issues?

Metrocast phone service seems very high, and was thinking about Vonage as an alternative.

Would like to hear some feedback, both pros and cons about Vonage service.

Thanks,
BD
