Using portable toll free numbers.
You have the ability to change your forwarding toll free phone number at any time through the Internet or over the phone when you travel. The FCC now requires that 800 numbers be portable, so that subscribers can port their numbers to a traditional phone line, allowing one to receive both direct calls and forwarded calls on the same phone. The numbers may remain in assigned status until changed to working status or for a subscriber to sell them for a maximum of six months. Assigned toll free number are telephone numbers that can be held by subscribers who do not have a year-round need for one of these numbers.
