From the Roanoke and Botetourt Tel. Co. directory (serving Troutville, etc., just north of Roanoke, Va.; phone 703-992-2211): Custom Calling Features: Call Waiting Call Forwarding 3-Way Calling Speed Calling Do Not Disturb Automatic Wake-Up Eldercare Package Rate (All Of The Above Features) I continued north on U.S. 220 and came to the CFW Tel. Co. directory for Clifton Forge-Covington, Va. (also Potts Creek, which is apparently nearby but which I can't yet find on a map). It includes: Toll Control Toll Denial Both of these prevent 0+ and 1+ calls, except that the former will permit such calls with the proper user-defined access code. For the latter, it is necessary to warn the customer that among the prohibited calls will be 0 for the operator in an emergency or when in need of help in calling.
