How do I change the IP to static in VitalPBX 4? 

By default, our system’s IP address in Debian is obtained through DHCP, however, you can modify it and assign it a static IP address using the following steps: 

1. Edit the following file with nano, /etc/network/interfaces. 

nano /etc/network/interfaces 

Change 

#The primary network interface 

allow-hotplug eth0 

iface eth0 inet dchp 

With the following. 

#The primary network interface 

allow-hotplug eth0 

iface eth0 inet static 

address 192.168.1.200 

netmask 255.255.255.0 

gateway 192.168.1.1 

Save and Exit 

2. Enable the interface. 

ifup eth0 

3. It is recommended to restart the server. 

reboot
