When an area code splits, some of the telephone numbers change to the new area code. There is a period of permissive dialing in which calls placed using either the old or new area code will complete. After permissive dialing ends, calls placed using the old area code will receive a recorded message instructing the caller to redial using the new area code. When that recording is disconnected, calls made using the old area code will fail, or will reach a wrong number.
