This page explains how to configure backup
routing for SMS messaging using the graphical user interface of the
Ozeki NG - SMS Gateway software. Backup routing can be used to send outgoing
messages on a different connection in case an error occurs in the default
For example if you have two GSM modems attached to your computer, you can send
SMS messages on the first one in case of normal operation. If you create a backup
route, for the second modem, it can take over the place of the first modem
in case the first modem fails.
To achieve this functionality, you must take a simple configuration step
to modify the outbound routing table of Ozeki NG SMS Gateway.
To configure backup routing all you have to do is add a new route to the
outbound routing table. When you add this route, click on the advanced tab
and select which route will it backup (Figure 1.)
