For the past two years, I have been working on and off on a high
availability cluster module for FreeSWITCH. If you would like to see
HA built into FreeSWITCH directly, instead of dealing with Pacemaker +
Corosync or other 3rd party systems, please check out the module,
voice your support, provide feedback and suggestions, and consider
supporting it.

Some advantages over a 3rd party solution like Pacemaker include:

- Sub-second failure detection and response (meaning it can start
recovering calls less than a second after a failure occurs)
- Failure detection is built into FreeSWITCH so it can detect
conditions which 3rd party modules cannot detect
- One shared configuration file between all nodes (no per-node IP
configuration required)
- No fixed number of nodes
- Graceful migration of calls with a maintenance mode (requires DNS)

These are just some of the benefits of building a FreeSWITCH-specific
HA system. For additional details about the project, please visit:


If you would like to see this project come to fruition, please
consider financially supporting it through Kickstarter:


Thanks in advance for anyone who contributes, either with just a
shout-out, with feedback and/or suggestions, and especially to those
who pledge some financial support.
