I use Vonage for VoIP; service allows you to use your existing copper
wire telephone handset to make and recieve phone calls over the
internet. Must have high speed internet access to ensure best phone
quality.

I have been using the service for 7-8 months, and I would never think
about going back.

Nothing is perfect though; lose your cable service and your phone goes
with it...Sending an email with an attachment while placing phone calls
effects sound quality, but all in all, the savings is too compelling.
