[Freeswitch-users] bind_server_ip issue

Fri Aug 14 05:14:29 PDT 2009

Hi Brian!

Thank you for your quick response. I ended up defining "local_ip_v4" at 
the top of vars.xml and set "bind_server_ip" to "local_ip_v4" as well. 
Is this the best way to go about selecting an IP address for FS to bind to?

In any case, even though it doesn't appear to affect operation, I am 
still getting this "IP change detected" somewhat periodically in my logs 
(running 1.0.4):
