OpenVox Asterisk FD180 IPPBX Failover Box - 8 Digital PRI T1 E1 BRI 1U w 1 ETH

{"type":"root","children":[{"type":"paragraph","children":[{"type":"text","value":"FD180 is a 8-port E1/T1/BRI interface failover appliance. 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).\n\nFD180 provides a reliable and flexible solution to Asterisk PBX.\n\nFD180 is controlled through an Asterisk loadable module res_failover.so. This module keeps sending “running” signal to redundant server 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 FD180 and thus FD180 will automatically switch to the redundant server."}]}]}
