VoIP technology is one of the continuously evolving technologies nowadays. It offers lower costs than traditional PSTN calls, and flexibility to use your existing network architecture to make phone calls.

Configuration steps

Before you begin, it is assumed that you have already downloaded and installed Trixbox in your environment.

Step 1.) Configure Trixbox

In this example, I have installed Trixbox in a server which IP address is 192.168.91.99. Open your web browser and navigate to the web interface of Trixbox.
In this guide it will be:
http://192.168.91.99/user/
Once it is done, click on switch next to User mode (Figure 2).

Enter the username and password to switch to Admin mode. By default, the username is maint and the password is password (Figure 3).

After login, click on PBX Settings at the PBX drop-down menu (Figure 4).

Click on Extensions at the Basic menu (Figure 5).

Select Generic SIP Device at the Device list, and click on Submit (Figure 6).

Provide the details of the extension you wish to create at the Add SIP Extension form. Enter the register name into the User Extension field, the display name into the Display Name field, and the password into the secret field (Figure 7). Once it is done, click on Submit.

I will use extension 100 to register Ozeki VoIP SIP SDK into Trixbox. Click on Apply Configuration Changes to save the changes (Figure 8).

By reloading the config file, your settings will come to effect in Trixbox. Click on Continue with reload to apply your changes (Figure 9).

By reloading the configuration, the configuration of Trixbox is done, and you can start to configure Ozeki VoIP SIP SDK.

Step 2.) Configure Ozeki VoIP SIP SDK

Before you start to configure Ozeki VoIP SIP SDK, it is assumed that you have already downloaded Ozeki VoIP SIP SDK from the download page and installed in your computer.

By default, the Demo Application will be installed into your computer. Start the demo application and provide the extension details into the SIP Account Settings tab, and click on Register (Figure 10).

You can see the successfully registered line at the Phone Lines section. Dial an extension (e.g. 101) and click on Pick up (Figure 11). Extension 101 is a traditional desktop phone, which is registered to Trixbox PBX.

At the destination phone you can see an incoming call from Ozeki VoIP SIP SDK. The incoming call is routed through Trixbox PBX (Figure 12).

After the destination phone is picked up, the call state will change to InCall. The active phone call will be visible at the Phone Calls section (Figure 13).

Conclusion

Now the configuration is done, and you have a working system which is connected to Trixbox PBX.
