NOTE:
• When using the External Gateway function, use version 1.30 or later of the RS-MS3W/RS-MS3A application
software.
• The caller station cannot communicate with the called station when:
- The caller station is using an earlier version software or firmware.
- The called station using an earlier version software or firmware.
- The called station calls through a local repeater instead of using the Terminal or Access Point mode.

with the caller station.
