Land Mobile Radio (LMR) systems that support telephone interconnect many times do not have the sophisticated ability to internally track and generate accurate long distance phone charges should the system subscribers wish to place calls outside their normal telephone calling area. This is so since the phone bill is a function of many variables such as distance, time of day, and of course, duration. In order to provide the subscribers with long distance dialing capability, it is common for these subscribers to access a long distance phone network by dialing a local access number. Several long distance carriers are available that offer competitive rates. Subscribing customers receive their own ac- count number, which they enter upon accessing the long distance carrier's network through that local access number. The charges for the long distance calls are hence handled by the long distance carrier and are periodically mailed directly to the customer.
