Loosing Static IP address after reboot on FreePBX server

Hi All,
I am facing an issue with static IP getting lost whenever I reboot server. So whenever I reboot my Asterisk FreePBX V 12.0.76.2, I loose IP address, though it is still available under /etc/sysconfig/network-scripts/ifcfg-eth0 file.
Next I have to restart network by “service network restart” and IP address comes back.

Can someone please help me to troubleshoot this issue.

thanks.

I think I have the same problem?

I have many CentOS 6.x hosts (sans FreePBX) and have experienced similar issue/s with “lost” IP address/es.
Some static, and some DHCP.
You may find this wrinkle is responsibility of the “upstream North American Linux vendor”.
