OpenVox FB40 4-port ISDN BRI interface failover box

FB40 is a 4-port ISDN BRI interface failover box. It can better protect the unpredictable problems happen to the Asterisk PBX. It will provide an effective way to backup the Asterisk PBX when undesirable changes are detected (often when Asterisk fails or power-off of the system). FB40 provides a reliable and flexible solution to Asterisk PBX.



FB40 is controlled through an Asterisk loadable module res_failover.so. This module keeps sending "running" signal to FB40 when Asterisk is running. Once Asterisk is down or system power is cut off, the module will not be able to send out the "running" signal to FB40 and thus FB40 will automatically switch to the standby server.
