Google Voice

Excerpt:

Google Voice wants to be the center of your voice communications. The Web-based service combines a lot of things: a permanent follow-around phone number; voice mail with transcriptions; and text messaging, to name a few. What it lacks—consistently high call quality, full recording capabilities, flawless conferencing and transcription—prevents it from being truly comprehensive. But that's just for now. And it's so close as it is that it earns our Editors' Choice for a unified messaging solution

The central feature of Google Voice is the single, permanent, virtual phone number. When called, that number simultaneously rings any or all of your physical (and verified) phones. The feature is just about perfect at what it does.
