Call forwarding can be useful when you won’t be near your phone. Callers can dial your normal number, and the phone system will forward their calls to a second line. You can activate call forwarding from your FairPoint phone or from another phone line. You also can set up call forwarding for all calls using a dialing menu. If you want to activate a busy line or no-answer call forwarding, you will need to call FairPoint to set up the feature.
