Failover Appliances

Digium's Redundancy Series (R-Series) products enable physical-layer failover of analog and digital telephony connections.

R800 (Analog)

R-Series failover appliances allow Asterisk users and integrators to build fully redundant communications systems. R-Series devices handle the physical redirection of PSTN circuits in the event of a catastrophic hardware or software failure. Tightly integrated with monitoring and resource management software, the R-Series failover appliances can switch PSTN traffic within seconds of a service interruption. A pair of Asterisk-based servers, cross-connected through an R-Series appliance can achieve 99.99% availability at a fraction of the cost of other redundant phone systems solutions. The R800 provides failover capabilities for analog circuits.

 

R850 (Digital)
