[Opensim-users] freeswitch problems (talk button)

Yes, I think you're right - there are a couple of freeswitch errors and 
these
can be ignored. I managed to get my installation up and running with 
local help
on the procedure. There are 3 key lessons learned on our end:

 1) One must use numeric IP addresses rather than domain names in 
Opensim.ini
      in the [Freeswitch] area.      Other aspects of OpenSim admit 
domain names
      without issue (ie. Region files) but not here.

 2) There a bit in the landflags field in Mysql. I could not set this 
bit through two
      different clients; however, there is a sql command that will set 
it. It is a hack,
      but works. All of the videos and online documentation regarding 
enabling voice
      simply didn't work.

 3) Routers need to be configured correctly on the client where those 
routers include
     firewalls. It is not simply a matter of 5060 - there are more ports 
to specify.

I am going to write something up on the next few days..
