What do I need to get started?

• A high-speed Internet connection - broadband, like cable or DSL
• A touchtone phone - any touchtone phone will do.
• A Butterfly phone adapter - the device that connects your high-speed Internet to your phone. Learn more about the Butterfly phone adapter.

How does Butterfly work?

Butterfly routes your phone calls over the Internet using Voice over Internet Protocol, rather than telephone lines. But even though your phone uses the Internet, it has nothing to do with your computer. In fact, your computer doesn't have to be on to use Butterfly. The people you call don't need to have Butterfly or the Internet to get your call - just a phone. And when someone calls you, your phone rings as usual.

Setup is easy. Just connect the Butterfly phone adapter to your high-speed Internet and connect your telephone to the adapter.

Why is Butterfly better than a regular phone service?

• Call around the world for less - exceptionally low per-minute rates
• Portable - you can take your Butterfly adapter with you when you travel.
• Keep your existing number - most numbers can be transferred to Butterfly.
