[Freeswitch-users] Load-Balance FreeSWITCH with Ultramonkey

[Mike van Lammeren]

Guess what? I have two FreeSWITCH servers working behind UltraMonkey, using
heartbeat and ldirectord for load-balancing, fail-over and high
availability! I'm probably not the first one to do it, but as near as Google
and I can tell, I'm the first one to write about it.
Here's how you can duplicate my setup:

1. Install Ubuntu Server 8 on four machines, either real or VM.
2. Compile and install FreeSWITCH v1.0.4 from source on two machines,
following these instructions:
http://wiki.freeswitch.org/wiki/Ubuntu_Quick_Start
<http://wiki.freeswitch.org/wiki/Ubuntu_Quick_Start>3. Configure both
FreeSWITCH boxes, and make sure they are both working.
4. Follow (most of) these instructions from Daniel Aliaman's blog. They were
written for Asterisk, but since a SIP connection is a SIP connection, most
of the document applies to FreeSWITCH:

<http://www.danielaliaman.com/blog/files/ultramonkeyasterisk.pdf>The one
problem I ran into was the IP address and port to which FreeSWITCH was
bound. The default is to use the primary address, which works great
out-of-the-box for everything else. When a client tried to register, all it
got back was an ICMP error -- Destination Unreachable, Port Unreachable.
That error is returned when no sockets are listening for UDP packets. To get
FreeSWITCH to listen for your Virtual IP, you need to set it in two places:

5. In /opt/freeswitch/conf/vars.xml, set "bind_server_ip".
6. In /opt/freeswitch/conf/sip_profiles/internal.xml, set "sip-ip".

That should do it! If you have any success, please report to this list.

Keep in mind that if you want to do something like conferencing between two
registered clients, then you have to deal with the fact that the clients may
or may not be on the same box.
