ABSTRACT:
An intercept arrangement by which on calls incoming to a key telephone system the calling party is provided with one and only one complete recorded message within a relatively short time so that the number of abondoned calls caused by excessive delays in answering is reduced. The arrangement includes ring counting, transfer and intercept trunk circuits on a one-per-line basis and a common intercept recorder. The trunk circuit has a monitor feature to provide a form of calling party release for all offices, and a standby-music facility which becomes effective after the transmission of the message.
