Digium R850 Digital Failover Appliance

The Digium R850 (1R850F) is a digital failover appliance which connects a primary and a backup Asterisk server and allows Asterisk administrators to create high-availability solutions that insure uninterrupted business communications, even in the event of a catastrophic hardware or software failure.

Digium R800 Overview

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. The R-Series family consists of 2 models, the analog R800 appliance and the digital R850 appliance. Each model supports eight (8) public switched telephone (PSTN) circuits. The appliances delivers PSTN circuits to each Asterisk server via Digium’s telephony interface cards. Management and failover communications between the Asterisk Servers and the R-Series appliance is done using a set of USB connections, which also provide power — saving energy costs over the lifespan of the appliance.
