Managing multimedia sessions including surveying anomalies representing illicit uses of a determined signalling protocol, determining reactions in relation to the identified anomaly, collecting all requests exchanged between a client terminal and a proxy server, analysing collected requests for detection of anomalies, through the use of a plurality of indicators each associated with one of the identified anomalies, and in the event of the detection of at least one anomaly, triggering by the proxy server of a reaction corresponding to the detected anomaly, the reaction including real-time action during the communication concerned by the message containing the anomaly. The method therefore allows the real-time detection and filtering of hidden channels utilised in a signalling protocol such as SIP.
