You can restrict your telephone line so that it will not dial long distance toll calls and/or seven digit Extended Community Calls (ECC). Calls will complete to no charge local numbers, 800 type and 911 calls. To over-ride the toll restriction, you listen for dial tone and enter *13 and then enter your Personal Identification Number (PIN), following by the "#" key. Now dial any Toll or ECC number to be called that upon completion is billed to the customers line. Restricting access to the PIN restricts calling to only authorized callers.If you need to change your PIN number it can be changed by getting dial tone, entering *12 and dialing your current PIN followed by the "#" key and then entering your new PIN number followed by the "#" key. Then hang up.
