Xorcom’s XR3000 is designed and manufacturer for the enterprise grade application. Featuring the ability to support up to 1,000 users and the only commercially supported hot failover solution on the market, Xorcoms XR3000 (pictured), XR2000 & XR1000 series IP PBX’s offer hardware reliability unmatched in the VoIP arena.

Through the use of an external Astribank channel bank and USB connections interfacing with the servers, the XR Series PBX’s allow you the ability to achieve hot failover without a huge amount of additional labor or hardware.
