If you have only one network card inside your system, its device name is eth0, it’s configured and only IPV4 is important to you then there should be nothing to do for you at this stage. If multiple network cards are present, your network card does not use eth0 for its device name or you need IPv6 then the only parameter you need to change at this moment is the listening address for your SIP services.

To do this, you have to specify the interface where your listening address is configured, which you can do with the following command (assuming your public interface is eth0):

ngcp-network --set-interface=eth0 --ip=auto --netmask=auto --hwaddr=auto
ngcp-network --move-from=lo --move-to=eth0 --type=web_ext --type=sip_ext --type=rtp_ext --type=ssh_ext --type=web_int

If you want to enable IPv6 as well, you have to set the address on the proper interface as well, like this (assuming you have an IPv6 address fdda:5cc1:23:4:0:0:0:1f on interface eth0):

ngcp-network --set-interface=eth0 --ipv6='FDDA:5CC1:23:4:0:0:0:1F'

If you haven’t fully configured your network interfaces, do this by adapting also the file /etc/network/interfaces:

vim /etc/network/interfaces

Add or adapt your interface configuration accordingly. For example, if you just want to use the system in your internal network 192.168.0.0/24, it could look something like this:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
        address 192.168.0.10
        netmask 255.255.255.0
        gateway 192.168.0.1
        dns-nameservers 8.8.8.8
        dns-search yourdomain.com

Reboot the server to apply the new network configuration:

reboot

In order to apply the changes you made to /etc/ngcp-config/config.yml, you need to execute the following command to re-generate your configuration files and to automatically restart the services:

ngcpcfg apply 'added network interface'

During installation, the system user cdrexport is created. This jailed system account is supposed to be used to export CDR files via sftp/scp. Set a password for this user by executing the following command:

passwd cdrexport

The installer has set up a MySQL database on your server. You need to set a password for the MySQL root user to protect it from unauthorized access by executing this command:

mysqladmin password <your mysql root password>

For the Administrative Web Panel located at https://<your-server-ip>:1443/login/admin, a default user administrator with password administrator has been created. Connect to the panel (accept the SSL certificate for now) using those credentials and change the password of this user by going to Settings→Administrators and click the Edit when hovering over the row.

The Sipwise C5 installer will install mailx (which has Exim4 as MTA as a default dependency) on the system, however the MTA is not configured by the installer. If you want to use the Voicemail-to-Email feature of the Voicebox, you need to configure your MTA properly. If you are fine to use the default MTA Exim4, execute the following command:

dpkg-reconfigure exim4-config

Depending on your mail setup in your environment (whether to use a smarthost or not), configure Exim accordingly. In the most simple setup, apply the following options when prompted for it:

You have a typical test deployment now and you are good to go, however you may need to do extra configuration depending on the devices you are using and functionality you want to achieve.

modules:
  - enable: yes
    name: dummy
    options: numdummies=2

ifconfig dummy0 192.168.2.2 netmask 255.255.255.0

auto dummy0
iface dummy0 inet static
address 192.168.2.2
netmask 255.255.255.0

ngcp-network --set-interface=dummy0 --ip=auto --netmask=auto
ngcp-network --move-from=lo --move-to=dummy0 --type=sip_int --type=web_int

ngcpcfg apply 'audiocodes devs workaround'

To test and use your installation, you need to follow these steps now:

Please read the next chapter for instructions on how to do this.
