UDP Hole Punch
When not using this function, set “UDP Hole Punch” to “OFF.”
• A few minutes* after the call, the caller station cannot receive from the called station. In this case, the caller
station must transmit to the called station again.
* Less than 3 minutes, depending on the router.
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.
• Even if using the latest version, the called station needs to forward port 40000 when connecting to the
Internet using a router, or to use a device assigned a static or dynamic Global IP address to communicate
with the caller station.
