[Freeswitch-users] How do I set my FS internal ip address to a "static" value.

[clif at eugeneweb.com]

Hi Gang,

I've been struggleing with this also. Actually I can get it to bind to my 
address, the problem is it randomly drops my calls. :-(

I have a FS running on a box with a static IP and I can start a call between 
two extensions and it will go for hours. Then I add anther interface say eth0:0 
with a new static IP and reconfigure my phones and FS to use that, and the 
calls drop after about 15-20 mins. Though it's pretty random.

Here is my setup. I have Debian Linux 2.6.23.1 kernel, and freeswitch-1.0.1. 
Here is my /etc/network/interfaces:

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
auto lo
iface lo inet loopback

# The first network card - this entry was created during the Debian 
installation
auto eth0 eth0:0
iface eth0 inet dhcp
iface eth0:0 inet static
 	address 192.168.0.249
 	netmask	255.255.255.0
 	gateway	192.168.0.254

The only change I made to the FS config is in Vars.xml. I added this line close 
to the top:

<X-PRE-PROCESS cmd="set" data="local_ip_v4=192.168.0.249"/>

Here is the console log of the call being dropped:

There is an older thread that says one should set
<X-PRE-PROCESS cmd="set" data="bind_server_ip=192.168.0.249"/>
but in this (later) thread is says only Jingleling usese that variable.
ie. see:
http://www.mail-archive.com/freeswitch-users@lists.freeswitch.org/msg00695.html
http://www.mail-archive.com/freeswitch-users@lists.freeswitch.org/msg07345.html

So what do you think causes this? What is the correct way? ;-)


 	Thanks,
