In a system in which terminals having mutually differing communication attributes perform communication so as to bridge one or a plurality of networks, to provide a method for automatic capture of a communication attribute converting apparatus in a switching apparatus for the control of automatic capture and control of communication attributes of the terminals, if there is a communication attribute converting apparatus which is capable of converting the communication attributes in a station containing a calling terminal, the convertible communication attributes are entered into the information elements of a call setting message of a call setting message and the message is sent to the station containing the receiving terminal. At the station containing the receiving terminal, when this call setting message is received, if there are communication attributes which can be converted and these communication attributes coincide with the communication attributes of the receiving terminal, a request to capture a communication attribute converting apparatus which is capable of converting the communication attributes of the calling terminal is entered into the information elements which are used for transfer of control information between networks and sent to the station containing the calling terminal. At the station containing the calling terminal, a communication attribute converting apparatus is captured in response to this capture request.
