Overview
HAAst is software package designed specifically to create a high-availability cluster out of an any pair of Asterisk servers. HAAst can detect a range of failures on one Asterisk server and automatically transfer control to the other server, resulting in a telephony environment with minimal down time.HAAst is a 100% software solution, with switchover in seconds. Built-in intelligent network control allows for a single IP address to be shared between peers, so clients/phones automatically connect to the active Asterisk server without change. Built-in replication and synchronization between servers also reduces maintenance and support activities.
HAAst is an easy to use solution, with shell (command line), telnet, socket, and web interfaces, suitable for beginners and experts alike. HAAst is ideal for demanding telephony environments like call centers, emergency 911 operations, medical facilities, and mid-to-large size businesses, as well as small-businesses looking for high PBX uptime using low-cost off the shelf components.
HAAst does not require any other High Availability/heartbeat software, nor require use of shared disk/block level disk sharing etc. HAAst also does not require any other specialized hardware so there is no single point of failure. HAAst is robust in functionality but simple to set up and use.
HAAst is available in Free and Commercial editions. The Free edition is suitable for companies wanting to test if the basic functionality & compatibility meets their needs. In addition, the Free edition is a functional and useful high availability add-on for SOHO environments, more capable that any other DIY scripts, etc. The commercial edition is suitable for companies with critical telephony uptime requirements including call centers, 911 emergency centers, hospitals, etc.
