PROBLEM TO BE SOLVED: To provide a remote call direction revision system placed in the inside of a local access network that sets the direction of a data traffic addressed to the internet to a channel directly connecting to the internet. SOLUTION: This call direction revision system has a processing module 134 accessing stored data for receiving protocol information ancillary to a call by a subscriber's equipment. The processing module 134 generates a direction setting message, based on the protocol information and stored data. The call direction revision system is further provided with a direction setting module 136, configured to change the direction of the call from the subscriber's equipment. The direction setting module 136 receives a direction setting message from the processing module 134 and changes the direction of a call to reduce congestion, in compliance with the direction setting message, then the device in the local access network adjusts the call whose direction is changed. Thus, congestion in the inside of the local access network resulting from the data traffic addressed to the internet is reduced.
