The method comprises: detecting disconnection of the communication terminal from the active communication session; in response to detecting the disconnection, automatically recording the missed information exchanged between the one or more connected communication terminals remaining in the active communication session; detecting reconnection of the disconnected terminal to the active communication session; and delivering the recorded information exchange to the reconnected terminal, in response to detecting the reconnection.
