Abstract: Apparatus (24) for connecting an outside caller (10) to an extension (14) of a local exchange (16) having a direct inward system access (DISA) feature includes a processor (90) and a memory (93) coupled to the processor (90) for storing at least one predetermined security code. A dialing information receiver (58) is controlled by the processor (90) to receive dialing information input from the outside caller (10). A second memory (94) is coupled to the processor (90) and the receiver (58) for storing the dialing information. A transmitter (58) is coupled to the processor (90) and the local exchanger (16) for transmitting second dialing information related to the dialing information to the local exchange (16). The processor may make a correlation between the dialing information and the second dialing information, or the dialing information may be passed through unchanged as the second dialing information.
