Abstract

La présente invention concerne un système d'enregistrement d'appels téléphoniques et de récupération d'appels enregistrés qui enregistre les conversations téléphoniques et stocke les conversations enregistrées en vue de leur récupération ultérieure. Le système de l'invention comprend un ou plusieurs serveurs couplés au RTPC, mais de préférence séparés des commutateurs des compagnies téléphoniques mobiles et terrestres. Un premier serveur assure les fonctionnalités de téléphonie, enregistrement d'appels et conférences d'appels. Un abonné qui forme un numéro de téléphone d'accès au premier serveur est acheminé vers ce serveur par le RTPC. L'abonné dispose de plusieurs options concernant le type d'enregistrement : enregistrement de type dictée, enregistrement automatique dès le moment où le numéro composé reçoit une réponse de la part de l'appelé, ou enregistrement sélectif d'une quelconque partie de la conversation par activation de touches pré-sélectionnées sur le téléphone. Les appels enregistrés sont alors stockés afin de pouvoir ensuite être récupérés par l'abonné, par exemple sur un serveur de stockage. Dans un mode de réalisation, l'abonné peut également enregistrer les appels reçus.
