[OpenSIPS-Users] Input on my loadbalancer configuration

[geoffreymina at gmail.com]

Thank you very much for taking the time to look over my configuration. I  
just want to make sure of something. I replied to my own original message  
with a greatly enhanced configuration. I realized the first was missing a  
huge amount of logic after studying up on OpenSIPS for 2 days. Were you  
commenting on the original message, or the second message? Based on my  
testing, i experienced slightly different results than you described.

What I am seeing (based on the second config) is that only the initial  
INVITE falls into the route(1) block, which is the way I intended it. This  
means only the INVITE requests are routed via the ds_select_dst() call to  
the dispatcher. All subsequent messages fall into my loose_route() check  
and are simply relayed via t_relay().

I included a little snippet of the logging I do via the xlog calls. One  
thing that confuses me is that based on my configuration and my logs, I  
never explicitly relay the TRYING or OK messages. I set up my  
onreply_route[1], but all I do is log that I got the reply. I did this  
because regardless of what I do here, the UAC which requested the INVITE  
gets the TRYING and OK messages properly. Is there something in the tm.so  
that implicitly handles these, or am I missing some big picture element  
here.

Thanks!
Geoff
