I'm also interested in this topic. Obviously there are some things which are harder to failover than others, like event socket connections, or agent queue states, but what about registrations and A-leg + B-leg type calls, where the media does not flow through FreeSwitch? Are there mechanisms for 'loading' a list of registrations or call states into a FreeSwitch box? -- Dan White
This topic has been beaten to death recently. Search the archives for things like "redundancy" and "failover" and you'll see lots of discussions. The bottom line is that your needs will dictate how much time, effort, and money you are willing to sink into this. If you want professional assistance then email consulting@freeswitch.org. If you want to do your own research then I'd say start with the ClueCon videos, specifically Day 3, Presentation #5.

Those discussions are probably it. It goes something like: "I want hot failover. Can't FS just load state?" "No, we think it'd take about $100K of work, and considerable time" "Oh. XXX does it. I'd think we just need a database." "No, it'll take a lot of effort. Just use a SIP proxy and redirect traffic around. Run FS on OpenVZ to avoid scheduled hardware maintenance. There's a money back guarantee on FS anyways." So, until someone gets funding and dev time scheduled, it probably won't go anywhere. Now if someone shows up with the people to actually implement it and wants some pointers on where to start after having gotten into the FS core, then the responses might be slightly different. -Michael -----Original Message----- From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Dan White Sent: Tuesday, September 29, 2009 1:05 PM To: freeswitch-users@lists.freeswitch.org Subject: Re: [Freeswitch-users] Freeswitch Failover I've downloaded 0Kb in 56 minutes.
