CONFIGURING YOUR FREEPBX V13

Step by Step Guide

You are now all set on the Mission Control Portal side and are ready to configure your Telnyx trunk within your FreePBX V13 system.

Installation

Once you load the ISO onto your server or virtual machine, you'll have a few options to select for installation. We'll be doing a full install via asterisk 13.

1. Confirm your appropriate network settings.

2. Confirm your root password.

3. Wait for all the necessary packages to be installed.

4. More modules will be updated after successful internet tests.

5. Enter root and the password you created from step 2.

6. You'll now be provided with the URL you need to use in order to access the FreePBX web interface.

Basic Settings Configuration

1. You'll be brought to the initial setup and must enter in the username, password and admin email address in order to create your account.

2. Once you've created your account, you'll be brought to the dashboard. Select FreePBX Administration and enter your username and password. 

3. Follow the process to activate your FreePBX V13.

4. Select your default locales.

5. You'll be presented with some firewall details and other suggestions. You are welcome to set this up based on your requirements. 

Eventually, you'll be back at the dashboard and now see more details.

At this point you can now work on confirming network settings and configuring your SIP trunks and extensions.

Make your way to Settings -> Asterisk SIP Settings in order to confirm your network settings.

You'll want to ensure you populate the external and local network addresses under General SIP Settings and Chan SIP Settings.

Click Submit and then Apply Config.

Extensions

Make your way to Applications -> Extensions -> Add Extension -> Add New Chan SIP Extension. The Outbound CID is the number you purchased from your Telnyx Mission Control Portal. The extensions secret may need to be populated under the Other tab.

NOTE: This device uses CHAN_SIP technology listening on Port 5160 (UDP - this is a NON STANDARD port)

Click Submit and Apply Config.

For testing purposes, you can now use your SIP client to register with FreePBX using the username, password/secret and local IP address of your FreePBX.

Trunks

Make your way to Connectivity -> Trunks -> Add Trunk -> Add New Chan SIP Trunk.
You'll now be located in the General tab.

Enter a Trunk name, your Outbound CID and the maximum channels you'd like for this trunk.

Proceed to the Dialed Number Manipulation Rules tab.

Depending on your use case, we've provided a simple dial pattern US numbers below.

For US numbers:

  • prepend:1; match pattern: NXXNXXXXXX
  • prepend: blank; match pattern: 1NXXNXXXXXX

International: 

  • prepend: Country Dialing prefix; match pattern: NXXNXXXXXX
  • prepend:blank; match pattern: (Country Dialing prefix)NXXNXXXXXX

Proceed to the SIP Settings tab. In the sub tabs outgoing and incoming, you'll want to include the following below settings:

Outgoing SIP Settings for the trunk:

Inbound SIP Settings for the trunk:

  • type=friend
  • insecure=port,invite
  • host=sip.telnyx.com
  • dtmfmode=rfc2833
  • disallow=all
  • allow=ulaw

Outbound Routes

Make your way to Connectivity -> Outbound Routes -> Add Outbound Route.

Enter the route name, route CID and specify the Telnyx_IP trunk for this outbound route. Click Submit and Apply Config.

Inbound Routes

Make your way to Connectivity -> Inbound Routes -> Add Inbound Route.

Enter the route name description, DID associated with this route and specify the extension that should be associated when calls are received to the DID.

Click Submit and Apply Config.

That's it, you've now completed the configuration of FreePBX V13 IP Trunk and can now make and receive calls by using Telnyx as your SIP provider!
