Abstract
A local networking system includes a memory to store local address numbers of registered local terminals; a specified number checking unit to check, when the system receives a first dial number from an unregistered local terminal, whether the first dial number is the same as a specified number; a registration checking unit to receive, when the first dial number has been found to be the same as a specified number, a second dial number from the unregistered terminal, and to check whether a local address number corresponding with the second dial number is stored in a memory; a non-registration checking unit to receive, when such a local number has been found to be stored in memory, a third dial number from the unregistered terminal and to check whether a local address number corresponding with the third dial number is stored in memory; and a registration unit to allocate, when a local address number corresponding with the last third dial number is not stored in memory, the third dial number to the unregistered terminal as its local address number, and to store the third dial number in memory.
