People communicating with each other in remote places can easily connect their communication devices. For example, a user A of an IP telephone unit a 1 may have a desire to transmit a still image to a user B talking on an IP telephone unit b 1 . In such a case, from the IP telephone unit b 1 , the IP telephone unit a 1 obtains the facsimile number of a communication device belonging to user B which can receive still images, for example, a facsimile. The IP telephone unit a 1 can transmit the obtained facsimile number to the facsimile device a 2 connected by LAN. The facsimile device a 2 which has received the number calls the received facsimile number. In other words, the IP telephone unit a 1 which includes the communication control device obtains the communication address required for a third communication during a call, and notifies the communication device a 2 of the address with the second communication function.
