A good place to get a toll-free number (800, 888, 877, 866) number from would be Kall8. I have used them for the past 8 months and have just had them forward the calls to my cell phone. When my cell phone is off, it forwards to my e-mail's inbox where I download the message via mp3 or wav format. I'd be lost without Kall8... for $2/mo you can get a toll-free number and they only charge you 6.9¢ per minute.
