| Zusammenfassung: | A communication apparatus, which captures a line in response to an off-hook operation, includes a first adjustment unit, a detection unit, and a second adjustment unit. The first adjustment unit performs first impedance adjustment according to detection of the off-hook operation. The detection unit detects a line current and a dial tone signal. The second adjustment unit performs second impedance adjustment based on the line current according to a result of detection of the dial tone signal by the detection unit after the first impedance adjustment is performed by the first adjustment unit. |
