FreeSBC Initial Configuration

Applies to version(s): v3.0

Initial configuration of the FreeSBC is done through a web browser (Chrome, Firefox or other). Before starting, you need the following information:

• Product key: it has the format VTB-XXX-XXXX. If you do not have this key, please go to our FreeSBC Download site.
• Hostname of the unit. It is important to set the hostname correctly and not modify it later, otherwise you will need a new license
• Is the system used as a standalone unit or is it used in a Primary/Secondary configuration?
• Does the system require external transcoding? As an example, G.711 to G.729a transcoding
• Role of each of the network interfaces

Then, follow the procedure below.

Initial configuration of the FreeSBC

1- Open a web browser to the IP of your server, on port 12358. Example if your server address is 192.168.178.30, the URL would be:
http://192.168.178.30:12358
2- You will get the SBC Configuration Wizard and click on Continue


3- You need to accept the EULA agreement


4- Enter your activation key and hostname

 Note: No need to enter hostname for AWS 

5- Enter your SSH and WEB root password

 Note: No need to enter SSH password for AWS 

6- Select the configuration of your SBC - either standalone, or in a Primary/Secondary configuration

 Note: Not applicable for AWS 

7- If the system requires external transcoding, select it here. As an example, if the system needs G.711 to G.729a transcoding, then select yes.

 Note: Not applicable for AWS 

8- Here you will choose the role of the network adapters in the system here is a short description of each type:

• mgmt: Used for management of the system (suggested name: mgmt0)
• ctrl0: Used for communication with the external transcoding devices (suggested name: ctrl0)
• ctrl1: Same as ctrl0. Adds redundancy (suggested name: ctrl1)
• LAN/WAN: SIP/RTP access to private network (suggested name: LAN0) or public network (suggested name: WAN0).

You need to configure all IP interfaces. In case of doubt, configure them as management interfaces.

If 1+1 (control networks ctrl0/ctrl1) or multiple vlan interfaces are needed, make sure all of them are assigned to the appropriate MAC address taken from the Platform (VMware Instance settings or other)
