The R800 appliance provides failover capabilities for analog (POTS) circuits. Lines from the telephone company are terminated to the R800, which then delivers service to Digium interface ports on the active
server. In the event of a hardware or software fault on primary, the R800 redirects all circuits to the backup. Control signaling is handled via USB ports which also provide power to the R800, saving energy over the lifetime of the appliance.
R-Series appliances include all the tools necessary to build a fully redundant active/passive communications solution. If the primary server experiences a hardware or software fault, all telecom services will automatically switch to the backup server. The R-Series integrates with software to mirror file systems, manages the transition of a shared IP address and monitors system health between the primary and backup.
