<P>PROBLEM TO BE SOLVED: To provide a communication system, call control server, monitor, and program which automatically check a source and a destination to prevent human errors which occur the source and the destination are visually checked and thereby can prevent personal information and company's sensitive information from accidentally flowing out to a third party by wrong transmission. <P>SOLUTION: The communication system consists of a communication terminal which sends and receives a call using the call control server, and the call control server which converts address information received from the communication terminal into a corresponding address and then sends it to the other party's terminal to connect the communication terminal and the other party's terminal. When the address information is sent from the communication terminal to the call control server as call request information, the call control server determines whether the address of the caller's communication terminal is permitted to be sent to the address in the address information. Only when permitted, the address information is converted into an address and the address is sent to the other party's terminal to connect the communication terminal and the other party's terminal. <P>COPYRIGHT: (C)2007,JPO&INPIT |
