Abstract:
1. A communication apparatus through which voice communication can be performed, comprising: a line interface portion which receives and transmits data from and to an exchanger through a line that is connected to the exchanger and that allows bidirectional communication between the exchanger and the line interface portion and which includes a data access arrangement device having a detection circuit that detects at least one of a line voltage and a line current; a voice reproducing device which reproduces a voice that is based on voice communication data transmitted from the line to the line interface portion; a volume adjuster which adjusts reproduction volume with which the voice is to be reproduced by the voice reproducing device, on the basis of a detected value of the detection circuit; an adjuster which adjusts, upon closing of the line and connection of the communication apparatus to the line, the line voltage and the line current so as to fall within the specified range, on the basis of the detected value of the detection circuit; and an operation controller which operates the volume adjuster upon termination of the adjustment of the line voltage and the line current by the adjuster and which does not operate the volume adjuster until the termination of the adjustment of the line voltage and the line current by the adjuster.
