CTS4000 - Heavy-duty, enterprise grade dual server redundancy

TwinStar™ is a high availability solution that provides automatic detection of server failure and immediate switching of all telephony functions, including telephony interfaces, to a back-up server. It is compatible with any Asterisk-based PBX system that supports a USB 2 connection, and particularly suited for the Xorcom IP-PBX family. This quick and automatic failover process keeps downtime to an absolute minimum.

TwinStar Product Description
The TwinStar solution is comprised of two Asterisk servers with identical configurations, and Xorcom Astribank channel banks with dual USB ports. It features:

• Full dual-server redundancy for complete Asterisk PBX systems, including telephony interfaces
• Automatic detection of server failure and switching to backup server, within seconds
• Firmware-based switching mechanism that is not network-dependent

How TwinStar Works
All telephony interfaces are connected via the Astribank channel bank, which in turn, is connected to each IP-PBX via a USB 2.0 connection. During standard operation, the primary server is active. The firmware in the Astribank continuously checks the status of the primary server.
