The author seems to be incorrect in stating that the CG-200 supports two FXO lines. According to the manufacturer's literature, it only supports one. Also, the screen shots given do not match this device at all. Perhaps the author only tested the CG- 400 and assumed that the CG-200 was the same. But it does not appear to be. AUTHOR'S REPLY: Confirmed. However, the hack can be accomplished as written since only a single FXO interface is required to demonstrate the desired outcome of the hack. The screenshots are from the web interface of a Clipcomm CG-410, not sure of the firmware revision.
