When the default terminal determination unit 146 determines that the communication terminal 10 of the communication partner is the communication terminal 10 that notifies the incoming call with the default setting (S610: Yes), the output setting storage unit 137 stores the incoming call notification unit 130. The incoming call notification determined by the default setting is made (S630). The incoming call history storage unit 160 stores incoming call records.

  When the default terminal determination unit 146 determines that the communication terminal 10 of the communication partner is not the communication terminal 10 that notifies the incoming call with default settings (S610: No), the multimedia data presence determination unit 110 determines that the INVITE message It is determined whether multimedia data is recorded in a predetermined recording area (S615). When the multimedia data presence / absence determination unit 110 determines that multimedia data is included in the INVITE message (S615: Yes), the multimedia data extraction unit 120 extracts the multimedia data recorded in the INVITE message. (S620).

  Next, the incoming call notification unit 130 notifies the incoming call using the extracted multimedia data (S625). The incoming call history storage unit 160 stores incoming call records. On the other hand, when the multimedia data presence / absence determination unit 110 determines that the multimedia data is not included in the INVITE message (S615: No), the incoming call notification unit 130 sets the default setting stored in the output setting storage unit 137. An incoming call notification determined in step S630 is made. The incoming call history storage unit 160 stores incoming call records.
