I've used Google Voice for one of my companies since 2007, and it's been great. However, I replaced it with Grasshopper (http://www.grasshopper.com http://www.grasshopper.com) a few months ago and haven't looked back. It is much better for inbound calls and is well worth the $10/mo for the entry-level plan. You can setup an 800 number (or a vanity 800-number for $30), and record an entire phone tree for various "departments" like support, sales, etc. Starting out as a 1-man team, all of these extensions routed to my own cell phone of course. But then as I grew, it was easy to login and change the destination of each extension to various team members. Both of my companies are primarily B2B, so being able to give the user experience of having a stable central hub, when we in fact work mostly remotely, is comforting to existing and potential clients. Without this, we'd have to try forwarding calls to each other's cell phone numbers, or telling the client to try dialing the other person's number directly, both of which are simply unacceptable. The one downside of Grasshopper is that, as of now, you are still unable to make outgoing calls through the number, since it doesn't have a GV app for Android or iPhone.
