I'm happy to say that all the phones in my life now use google voice. The gist of GV is that google gives you a number which can route to your cell, home, or office. Depending on who calls, you can have google ring any or all of your phones. Alternatively, if you don't really want to talk to the person, you can have it go straight to voice mail. Think spam filter for the telephone. There are lots of other little bonuses including:
- Free domestic calling
- Cheap international calling
- Machine voicemail transcription that is sent to your email (not super accurate but usually good enough)
- Do not disturb mode
- Free text messages
- GV widgets for website like the one at the bottom of this page (I have it set to go to voicemail)
