In an apparatus for connection control between two terminals, a communication unit transmits or receives a connection control signal to or from the terminals. A storage stores media format information usable on the two terminals, which are to be supplied with the media format information on media formats converted by a media format converter. A media format information supplementing unit references the media format information storage, based on the connection control signal received from the terminal, and verifies a possible presence of common media format information usable by the terminals to be interconnected. If there is no common media format information, predetermined media format information is supplemented to the connection control signal, and a resulting connection control signal is delivered to the communication device. Thus, media negotiation may be made even when media formats usable on the two terminals differ from each other.
