Abstract (en)
[origin: FR2764762A1] The invention concerns an apparatus or subset interposed between the telephone receiver line or antenna and the receiver itself, filtering calls, using more or less lengthy time-out intervals, whereof the duration is selected by the user and can be of several minutes, according to several adjustable modes. During these time-out intervals, a pre-programmed message is transmitted to the caller, without putting him through and therefore without disturbing rings for the recipient. Said time-out interval system obviates the drawbacks of filtering systems with imperative access codes or red-listed sets. The most complete embodiments correspond to a flexible automatic switchboard.
