Thanks Muhammad, that would be a good idea. However, I'm trying direct routing mode of IPVS for load balancing along with Heartbeat for HA. Could anyone of you guys suggest a better way to implement Load balancing and HA for FreeSwitch? Thanks On Wed, Jul 4, 2012 at 1:36 PM, Muhammad Naseer Bhatti <nbhatti@gmail.com>wrote:

We did this little trick by adding an additional channel variable which holds the actual IP address forwarded by OpenSIPS. You can later play around with this variable to do post processing etc.

I think I got it! it's explained here<http://www.ultramonkey.org/3/lvs.html>in packet forwarding section. Changing the source won't happen.

Dear all,

I tried OpenSIPs for load balancing. I works just fine, but as it is mentioned here,<http://wiki.freeswitch.org/wiki/Enterprise_deployment_OpenSIPS#CDRs>OpenSIPs sends requests from itself. How about Ultramonkey? Does it change the source too, or it just manipulate destination of registration packets?

Thanks, Hanie

You can also try DNS based fail-over and load balancing, works perfect for us. Thank you. On Fri, Jul 6, 2012 at 9:02 AM, A E G <all.eforums@gmail.com> wrote:

Not sure about HA, but the call distributor module: http://wiki.freeswitch.org/wiki/Mod_distributor used to work well for us ...haven't used it for a while now. Not sure if anything has changed in newer builds.

Yes, srv records would work but as you said, they don't know the state of you installation, I.e. up, down or indifferent. Also, I have found that there are not many carriers that support srv and those that do lack the full implementation. If it was me, I'd put openser or something similar in front of your freeswitch boxes which will act as a router, load balancer. The is nothing wrong with using heartbeat and corosync but your public ip would need to be on the same subnet for it to work correctly. Hope this helps. Oz.

Hello, What you mean by DNS based failover ? Short ttl on DNS A record may cause name resolution issues, isnt it ? How does it work ?

DNS SRV is a good way too, but its selection is kind of static (round robin and wight) and doesn't care about the servers' load: http://wiki.freeswitch.org/wiki/Enterprise_deployment_DNS_SRV Thanks On Fri, Jul 6, 2012 at 9:30 AM, Muhammad Shahzad <shaheryarkh@googlemail.com

Thanks, But I think distributor module works for routing calls after FS receives them. I plan to have a cluster of FreeSwitches, so that I can balance the load of my incoming calls.

Yes, but we had FS at the head-end of a cluster of FS boxes. No one said FS can only sit at the core ;) The other benefit you get with it is ALG type functionality (with some configuration). DNS isn't a good way to do this as it has no sense of context of what is being sent (SRV does though, but is not widely supported by many ISPs or domain name providers, unless you run your own DNS servers) and will blindly RR between IPs whether it is up or down or worse hung ...so if you have 3 machine farm, and one of them is hung, 1 in 3 calls will fail. Proper load-balancing should have context and awareness of the application as well the downstream server to which the call should or should not be sent to if it's not capable of servicing the call.
