[Freeswitch-users] Load-Balance FreeSWITCH with Ultramonkey

[Even André Fiskvik]

That's very cool Mike!

I'm going to try to configure four boxes with this as well (Btw, did  
you use physical hardware or virtualization?)
and see how it goes. I followed Daniel Aliaman's blog as well, but I  
can try it again with the tips
you provided on FreeSWITCH config to see if I can get it working  
properly this time.
We did the setup on CentOS, but I wouldn't think that would be any  
issue.

Perhaps you or we could write up a complete guide about this on the  
wiki since this is an scenario
commonly used? Also it would be great if we could outline possible  
issues (and even better solutions)
to this kind of setup with regards to stuff like conferencing,  
bridging between registered users and presence.


Best regards,
Even André
