Orders received by 10 am are shipped on the same business day. Mondays through Saturday.
FD140 provides a reliable and flexible solution to Asterisk PBX.
FD140 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 FD140 and thus FD140 will automatically switch to the redundant server.
