A radio apparatus, to be used as a first ending node of a communication network, is connectable to a hands-free apparatus by a local radio link to form a hands-free system. A call made on the hands-free apparatus for an second ending node in the communication network is sent to the radio apparatus through a control channel on the local radio link. The radio apparatus and the hands-free apparatus arrange a voice channel to be established on the local radio link. The call is then sent to the second ending node. In a case where no voice channel is established within a predetermined time period after arranging the voice channel, the radio apparatus cancels the call to prevent a connection between the radio apparatus and the second ending node from being kept and charged.
