• the relay apparatus comprising:
• processing circuitry configured to record the P2P communication when receiving the instruction,
• wherein the communication method of the P2P communication is at least one of three communication methods corresponding to:
• local communication without passing through a NAT, communication that traverses a NAT but does not use a TURN server, and communication that uses a TURN server.

A communication control method in a communication control apparatus connected to two terminals and to a relay apparatus that relays P2P communication performed between the two terminals, comprising:

• storing, in a memory, authority information including a communication method of the P2P communication permitted for each of the two terminals;

• storing, in a memory, authority information including a communication method of the P2P communication permitted for each of the two terminals;
• receiving a signaling signal mutually transmitted between the two terminals;
• and
• controlling the communication method of the P2P communication based on the authority information when receiving the signaling signal,
• wherein the communication method of the P2P communication is at least one of three communication methods corresponding to:
• local communication without passing through a NAT, communication that traverses a NAT but does not use a TURN server, and communication that uses a TURN server.

A communication control apparatus that is connected, via a network, to a terminal and to a relay apparatus relaying P2P communication performed by the terminal, and that controls communication performed by the terminal, comprising:

• a memory configured to store communication destination information including a communication destination permitted for the terminal;
• and
• processing circuitry configured to
• receive, from the terminal, a signaling signal that the terminal transmits when the terminal starts the P2P communication, and
• control whether to permit the P2P communication based on the communication destination information and the signaling signal,
• wherein the communication destination information includes address information of a communication destination permitted for the terminal or address information of the relay apparatus, and
• the processing circuitry controls whether to permit the P2P communication by comparing the address information of the communication destination included in the signaling signal with address information included in the communication destination information.
