Claim Text:
1. A communication management system, comprising: a memory configured to store, for each one of a plurality of communication terminals including at least a first communication terminal of a first type that uses a first communication protocol and a second communication terminal of a second type that uses a second communication protocol, terminal identification information for identifying the respective communication terminal, and candidate counterpart terminal identification information for identifying one or more candidate counterpart communication terminals that may be requested to start communication with the respective communication terminal, in association with each other; the memory being further configured to store, for the second communication terminal that uses the second communication protocol among the plurality of communication terminals, the terminal identification information of the second communication terminal, and address information indicating an address of the second communication terminal that uses the second communication protocol on a network, in association with each other; the memory being further configured to store session identification information for identifying a communication session, the communication session being carried by at least the first communication terminal that uses the first communication protocol and the second communication terminal that uses the second communication protocol of the plurality of communication terminals, and terminal identification information of at least the first and second communication terminals carrying the communication session, in association with each other; a receiver configured to receive a session start determination request that requests to determine whether to start a communication session with a third communication terminal that uses the second communication protocol from a conversion system, the conversion system including circuitry configured to convert between the first communication protocol and the second communication terminal in relaying content data to be transmitted or received through at least two of the plurality of communication terminals, circuitry configured to a transmitter configured to transmit a response indicating to start a communication session with the third communication terminal based on a determination result indicating that the address information of the third communication terminal matches one of the obtained address information, to the conversion system in response to the session start determination request.
