[Opensim-users] trying to set up freeswitch

In case its helpful, we have FreeSwitch workings fine across 3 
different Opensim.exe instances on separate hosts in a grid of 20 
regions.  The Opensim Wiki page and Opensim.ini.example file was 
altered as a result of our experience so look at that carefully for setup.

Additional notes that might help:

1. We established a simple OpenSim.exe on the SAME host as the 
FreeSwitch.exe service and put a single simple island on that (we 
called it "Talk") as some folks observed that FreeSwitch had problems 
with connecting for its CONFIGURED server lin to another server, and 
use THAT OpenSim.exe instance for the config setup with FreeSwitch.. 
not the main regions we run on other servers.

2. FreeSwitch provides service to all OpenSim.ex instances on any 
servers you wish even though its only configured fro one.

3. There is one FreeSwitch channel per region, change regions and you 
change channel.  So all users to talk must be on the same 
region.  Plots on one region share the region channel we think.

4. You appear as one user in the SL Viewers, AL other users appear as 
a single "user" with a coded name for the channel.

5. You must have voice enabled at the region, AND the plot 
level.  This is a pain, as the default setting in OpenSim is that 
PLOTS have voice turned off.  The standard viewers 1.23 and 2.x do 
not allow you to turn this back on, so you must use a third party 
viewer to turn on PLOT voice.  I have asked before that we change the 
default setting when a plot is created to have this on by default (or 
on if the region voice is on- which it is by default).

6. You definitely MUST start FreeSwitch.exe before the regions that 
you want voice to work on. It works fine over restarts without 
FreeSwitch being started again.

7. Rremember to configure for EXTERNALLY accessible IP 
addressed.  Use IP numbers fro FreeSwitch... and if there are 
192.168.x.x style local net addresses in there you will not get 
FreeSwitch to work with external users.

8. There are some red errors on startup of FreeSwitch as noted by 
gregor.. at least in our setup which appears to be related to a 
missing config file that FreeSwitch tries to retrieve from OpenSim 
(opensim-region-server-url:port/api/freeswitch-config) that is not in 
the OpenSim setup... We have (safely?) ignored those without problems...

You can test voice on regions on the Openvue grid if you wish... The 
Talk region is on same host as the FreeSwitch.exe service if other 
regions give problems.  The server is only a dual core Pentium 
Windows 32 bit OS machine so not that beefy remember, but has worked 
for 4 way calls for us.
