Clustered Asterisk with BioCluster

With promises and road maps to cluster anything that could be clustered as well as traditionally unclusterble devices, BioCluster peer-to-peer clustering engine, has come out with Asterisk Cluster solution.

BioCluster now in beta, is a peer-to-peer clustering platform for Asterisk, the Open Source PBX. It is meant to be installed on several machines together with Asterisk, and turns them into a VoIP cluster, which can then be managed as a whole, with data replicated across it. Thus there is no single point of failure, and machines can be easily added or removed from the cluster.

BioCluster Features

Among the features that BioCluster Free Edition 1.0 Beta supports are:

  • SIP extensions
  • Trunks: SIP, IAX2, Zap
  • Priority routes
  • Dialplan editing
  • IVR
  • User roles
  • Call recording
  • Music on hold
  • Sound files
  • Credits
  • CDR - tracking, queries, summaries, and sending to a central local or remote CDR database
  • Voice mail
  • Voice channels - monitoring active channels and hanging up channels

BioCluster Free Edition comes with a command line interface to configure various aspects of the cluster. BioCluster can be easily extended with various other PBX features, and its protocol can be adapted for clustering of other applications.

In addition to the above features, there are several commercial addons available for BioCluster. These can be obtained from Atelis, among them:

  • Web interface for managing the cluster (accessible through a web-browser)
  • Personal portal for each user, accessible through a web-browser, with ability to manage user's voicemail, recorded calls and call forwarding

The web interface with all above features can be previewed at the BioCluster demo.
