To get the IP address use the command

ip addr show dev eth0

  

 As a result you will get a block of data like this: 

3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast 
    link/ether 00:22:4d:ab:18:8c brd ff:ff:ff:ff:ff:ff 
    inet 192.168.0.64/20 brd 192.168.15.255 scope global dynamic eth0 
       valid_lft 125725sec preferred_lft 125725sec 
    inet6 fe80::222:4dff:feab:188c/64 scope link  
       valid_lft forever preferred_lft forever 

In this example the CXR1000 IP address is 192.168.0.64.   
Method 1: Set up a static IP address via command line. 

1.

 

Login into your system as root, as described above 

2.

 

Replace 1.2.3.4/24 and 1.2.3.1 with the required IP address (in CIDR format) and 
default gateway and then run the following command:  
 

nmcli con mod eth0 ipv4.method manual \ 
ipv4.address 1.2.3.4/24 ipv4.gateway 1.2.3.1

 

 

3.

 

Define the DNS server in the /etc/resolv.conf file. For example: 

nameserver 5.6.7.8

 

4.

 

Run 

systemctl restart network

 in order to apply the changes 

Method 2:  Set up a static IP address by using 

nmtui

 utility. 

1.

 

Login into your system as root, as it described above 

2.

 

Run the 

nmtui 

command and define a static IP address and the default gateway 

3.

 

Define the DNS server in the /etc/resolv.conf file: 

nameserver 5.6.7.8

 

4.

 

Run 

systemctl restart network

 in order to apply the changes 

Note

: Correct network parameters settings are extremely important for normal CompletePBX 

functionality.  
Always make sure that the 'localhost' is defined in the /etc/hosts file: 
127.0.0.1   

localhost.localdomain localhost 

Step 4: Configure the CXR1000 

If the unit is equipped with FXS ports they are configured as CompletePBX extensions starting 
from number 3001.
