Many options for a virtual phone number

Need another phone number?  Most people would answer no but recently I had to say yes to that question.  I needed a number that could reach me wherever I was but that I could occasionally forward to someone else to handle inbound technical calls.  I didn't want to use my cell number or my business line because I wanted to keep those calls coming to me or going to voice mail.  I needed a virtual phone number.  In looking around a bit I was surprised to find so many options.  Here's a short list (in no particular order) of the ones I kept past the initial Google search.

Google Voice

A friend of mine had Google voice so I asked him for an invite so I could try it out.  That's the end of the story.  Google Voice fit my need perfectly.  In fact, it's totally awesome and currently free unlike the other services listed above.
