Abstract
A control device may be connected in series or in parallel to a telephone for restricting or routing calls made from the telephone to take advantage of low cost carriers for intra-LATA calls. The serial or parallel connection of the telephone can be detected as well. The device may be programmed for routing depending on the geographical location of the telephone. The central receiving office of the local phone company can be prevented from routing the call by the use of interfering tones.
