Abstract
The present invention provides a PoC system which has the following capabilities: 1) it enables communication content to be confirmed afterwards; 2) by recording communication content in conjunction with information such as a caller identifier, it makes it easy to retrieve communication content afterwards; 3) it can record communication content only when this is necessary; 4) it can change as desired the criterion for deciding whether or not to record communication content; 5) it can record even during communications that include off-record content. Accordingly, when PoC group communication is taking place, the exchanged communication content is recorded during each session. Recording is only carried out when it is decided that recording is necessary. It is also possible to change whether communication content is recorded or not on a per-utterance basis. Communication content is indexed by session identifier and caller identifier, and a particular communication content can be fetched by specifying session and/or caller.
