TwinStar - High Availability Solution for Complete Asterisk-based Systems

P/N = LC0016

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 (such as: Xorcom XR2000 and XR3000). 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 minutes
  • 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. Watch our video demonstration...

If the firmware mechanism detects a problem with the function of the primary server, it immediately passes control to the backup server. All telephony lines are automatically recognized and activated by the backup server, and all communication in the organization is re-established within minutes.
