The SIParator fully supports load balancing and failover using DNS SRV and speeds up failover by monitoring SIP servers. In addition, the SIParators can be used in failover pairs, protecting from catastrophic failure. By synchronizing configuration and long time states (like SIP registrations), the idle device takes over at the Ethernet level should the active device fail. This Ingate failover method also protects against software faults, since it directly allows dropped calls to be setup freshly again. The largest Ingate E-SBCs (S95/S97/S98) are highly protected against hardware failure with redundant dual power supplies and RAID 1 hard disks.
