<p><P>PROBLEM TO BE SOLVED: To provide a communication control unit capable of registering a plurality of call terminals as call terminals allowing calls, and to provide a method of controlling communication and a communication control program. <P>SOLUTION: When a registration request signal for requesting registration to a registration list is transmitted from the call terminal, the communication control unit receives the registration request signal (S11: YES). When the communication terminal having transmitted the registration request signal has already been registered in the registration list (S15: YES), registration information in the registration list is updated (S19). When the communication terminal has not been registered in the registration list (S15: NO), the call terminal having transmitted the registration request signal is registered therein (S20), even when the call terminal to which the same SIP address as that assigned to the call terminal has been assigned has already been registered in the registration list, thus registering the plurality of call terminals to which the same SIP address has been assigned in the registration list. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
