Abstract

The invention relates to a secure public telephony system comprising at least one public telephone (10) which is connected to a telecommunication network (1) and a securement device that can monitor the exchanges of information between said public telephone and at least one part of the numbers called. The inventive system is characterised in that the securement device comprises a remote server (20). Said server (20) can be connected to the public telephone by means of the telecommunication network (1) and is adapted to transfer the information exchanged between said telephone and the numbers called.
