<P>PROBLEM TO BE SOLVED: To get an automatic setting function to function correctly regardless of a NAT device, and thereby to reduce time and labor for operation. <P>SOLUTION: According to an embodiment, a telephone system comprises a NAT router and a call control server. The call control sever belongs to a private network. The call control server comprises: a connection processing unit; a transmission unit; a determination unit; and a notice unit. The connection processing unit processes a connection request from a telephone terminal. The transmission unit transmits setting information corresponding to identification information given to the telephone terminal of the connection request source to the telephone terminal of the connection request source. The determination unit determines which the telephone terminal of the connection request source belongs to, a global network or a private network. The notice unit notifies a telephone terminal which is determined to belong to the global network of a global address of the call control server, and notifies a telephone terminal which is determined to belong to the private network of a private address of the call control server. <P>COPYRIGHT: (C)2013,JPO&INPIT |
