Setting up your Telnyx SIP portal account so you can make and receive calls:

Install FusionPBX (From FusionPBX)

Note: Video walkthrough for FusionPBX/Telnyx configuration coming soon. Check back as we update our docs.

1. (OPTIONAL BUT RECOMMENDED) Install a virtual machine

You only need to complete this section if you plan to run your FusionPBX on a virtual machine. If you don't, you can skip to section 2.

  1. Download and install the Debian network installer disk image and run it.

  2. Click on the New icon in the VirtualBox menu bar.

  3. This will start the New Virtual Machine Wizard. The first screen is just a welcome screen so click Continue to proceed.

  4. On the Name and operating system screen, provide the following:

    1. Name: You can give this any name you like

    2. Operating System: Linux

    3. Version: Debian (64 bit)

  5. Click Continue.

  6. On the Memory size screen, you can just use the default setting for the amount of base memory.

  7. Click Continue.

  8. On the Hard disk screen, you'll create a new virtual hard disk to use as your VM file system. Select Create a virtual hard disk now.

  9. Click Create.

  10. In the next screen, you'll specify the format for the virtual hard disk. Just use the default settings here: the native VirtualBox disk image (VDI) format.

  11. Click Continue.

  12. On the Storage on physical hard disk screen, you'll choose how your virtual hard disk is sized. The default option is is dynamically allocated, and this is the option we recommend.

  13. Finally, on the File location and size screen, choose the location and maximum size of your virtual machine disk. You can just use the defaults here, unless you require anything specific.

  14. Click Create. Welcome to your virtual machine!

  15. Click on the Settings gear at the top left of your new VM and find the Storage option in the left-hand navigation.

  16. Select the Debian file under the Controller: IDE.

  17. You'll see that the network ISO image is configured for your virtual machine and you can now start it. It will boot, and begin the Debian Linux installation process on the VM.

  18. After this completes, you can go to your VirtualBox homepage and hit the power "button" on the page. This will power it on and allow you to specify your desired configurations, such as preferred language etc. and once complete, you can install your FusionPBX. 

2. Install FusionPBX

FusionPBX can be installed on several different operating systems however we recommend using Debian. If you are installing Debian from scratch it will have prompted you during the installation phase to have created a root password. This will be the password you will enter when you run the command su root in the terminal.

  1. Visit this website that FusionPBX recommends for following the install script as it is much simpler and faster than previous ways.

  2. Run the following commands as root. This will run a scrip that installs FusionPBX, FreeSWITCH release package and its dependencies, iptables, Fail2ban, NGINX, PHP-FPM, and PostgreSQL.

    #upgrade the packages
    apt-get update && apt-get upgrade -y

    #install packages
    apt-get install -y git lsb-release

    #get the install script
    cd /usr/src && git clone https://github.com/fusionpbx/fusionpbx-install.sh.git

    #change the working directory
    cd /usr/src/fusionpbx-install.sh/debian

  3. At the end of the install script you will be instructed to go to the IP address of the server in your web browser to finish the install in the FusionPBX GUI. 

  4. Once you have opened a browser with the URL the terminal gave you, you should see a GUI where you will go on to configure FusionPBX. 

  5. Choose your language and click Next.

  6. Your event socket settings will be automatically detected. Click Next.

  7. Here you will need to enter a username and password as your login credentials for FusionPBX.

  8. Any writing in bold indicates that you must fill it in. At this point you will need to go back to the terminal and grab the details you would have seen, just above the server IP, that relate to the database username and password.

  9. Click Next.

  10. You'll be brought back to the login page where you will sign in with the username and password from step 7. 

3. Configure a FusionPBX trunk

Once you have the installation of your FusionPBX set up, It is now time to configure your PBX so that you can make and receive calls through Telnyx! 

  1. Go to the Advanced header and to Upgrade in the drop down list.

  2. Tick App Defaults and press the Execute button on the bottom-right.

  3. Go to the Accounts header, select Gateway, and provide the following details

    1. Gateway: Telnyx

    2. Username: The username from your Telnyx credentials based connection.

    3. Password: The password from your Telnyx credentials based connection.

    4. From User: The username from your Telnyx credentials based connection.

    5. From Domain: sip.telnyx.com

    6. Proxy: sip.telnyx.com

  4. Click Save. You'll be taken to a screen where you'll see that FusionPBX is now registered with Telnyx.

4. Create your extensions

  1. Now go to the Accounts header and select Extensions.

  2. Click the Add button to add an extension. The following image shows an example of what they should look like.

    Note: The Telnyx support portal automatically shrinks images, so if you have trouble seeing it, right-click on the image and select Open Image in New Tab to view it in full size.

  3. Once you've created an extension, you can click into it and change the password that was given to you if you'd like to.

    Note: Depending on your phone configuration, you may also wish to configure an outbound caller ID. You can apply this via the "Outbound Caller ID Number" field. For more information on the fields below, please visit FusionPBX's extensions documentation.

    Before configuring an outbound caller ID, you should be aware of some of the naming conventions standard for caller ID creation:

    • Your outbound Caller ID Name should be in capital letters. This will appears more clearly/visible on some devices.

    • You must NOT use any special characters, as they will not be displayed.

    • Some of regular Canadian providers will not show more than 15 characters. We suggest shrinking or adapt your caller ID.

    • Spaces are allowed in a caller id name.

  4. Click Save.

  5. Go to the Dialplan header and select Destinations.

  6. Click the Add button to add your destinations. 

    1. You'll want to add in a number that you purchased on your Portal account to Destination - Make sure to add a +1 in front of the number.

    2. Then for Actions, select an extension you created from the drop-down list.

  7. Click Save.

5. Configure inbound routing

In this step, you will configure an inbound calling route pattern that CompletePBX will require in order for you to receive inbound calls from your DID. Each DID will need to be associated with an inbound route. Multiple DIDs can be associated with the same route, but any single DID can only be associated with a single route.

  1. Go to the Dialplan header and select Inbound routes. Your inbound routes should be added automatically that relate to your destinations you created.

  2. When you click on any of the numbers you created as inbound routes you will see a dialplan like the picture that follows. (You will need to make sure that your number format is set to E164 on your connection you created in your Mission Control Portal.)

6. Configure outbound routing

In this step, you will configure an outbound calling route pattern that CompletePBX will use as a template, or set of rules, to follow for outbound calls associated with the route.

  1. Go to the Dialplan header and select Outbound routes.

  2. Click the Add button to create your different outbound routes.

  3. Create your outbound route using the following parameters:

    1. Gateway: Select Telnyx

    2. Dialplan Expression: Select the region you want to configure the dialplan expression for. i.e.: North America

  4. Click Save.

7. Register your extensions with a device

  1. Go to the Status header and select Registrations. At this point you will need to register the extensions you created with whatever device you choose. 

    In this example, we used Zoiper and Xlite softphone to register these extensions.

  2. All your registered devices will show up on the registration’s page. 

Both extensions are registered with the servers IP address so they can now make and receive calls internally via calling 1000 or 1001. Your inbound and outbound routes are set and you will be able to make and receive calls externally also.

That's it, you've now completed the configuration of FusionPBX and can now make and receive calls by using Telnyx as the SIP provider.
