ABSTRACT:
A communication system has a first communication terminal and a second communication terminal connected to a network. Communication can be performed by the first and second communication terminals in a plurality of modes. The first communication terminal has a detecting unit to detect calls that are refused by the second communication terminal and that are performed in a first mode when a second mode has been set. Based on the detection of the detecting unit, a first calling unit calls the second communication terminal in the second mode. Using the second mode, when the call from the first calling unit is accepted, a mode switching instruction unit instructs the second communication terminal to switch from the second mode to the first mode. Based on a response to an instruction from the mode switching instruction unit, a second calling unit calls the second communication terminal in the first mode. The second communication terminal includes a mode switching response unit. Upon receiving the instruction from the mode switching instruction unit, the mode switching response unit responds to the instruction using the second mode. After the response is returned, a mode switching unit switches the mode from the second mode to the first mode.
