Configuring VitalPBX

Here we will configure the VitalPBX through the web interface to properly route both incoming and outgoing calls to/from Callcentric. The information presented in this guide is based on Version 2.3.4-1 (Asterisk 16.4.0) of the VitalPBX software. If you are running a different software version, some of the menu options and settings may be different. This guide assumes that you have already installed VitalPBX and that you have access to the administrative web interface.

We recommend that you read each step through in its entirety before performing the action(s) indicated within the step.
STEP 1 Adding an extension
Login to the VitalPBX administrative interface and click on the PBX option that is located on the side menu bar. From there, select Extensions from the sub menu.



On this page enter the following: Extension Number, Extension Name, Password

After doing so, click the Save button to continue. Next, click the reload icon near the top right corner of the screen to apply the changes you've just made.

Note: You're free to modify the other settings on this page, however please note that the settings we provide in this guide have been tested/confirmed to work properly.



STEP 2 Adding a VoIP Trunk
Next we will create a new SIP trunk on your PBX. Select PBX from the side menu bar and then click on the heading labeled External and choose the sub-heading labeled Trunk.

In the trunk configuration page, please configure your settings in-line with those detailed in the screenshot below. After doing so, click the Save button to continue. Next, click the reload icon near the top right corner of the screen to apply the changes you've just made.

STEP 5 Additional Settings
For this step, you will need SSH Access to the server hosting your PBX to proceed. After you've remotely accessed your PBX's shell, navigate to the directory /etc/asterisk/ombutel. Using a text editor such as VIM or nano, copy and paste the following and save it as sip__callcentric_custom.conf (note there are 2 underscores between "sip" and "callcentric").

Important Note: It is imperative that you replace the value within the parentheses with your assigned 1777 number. For example, if your 1777 number is 17771234567, you will need to replace each 1777MYCCID below with 17771234567.

STEP 6 Configure and test UA (User Agent)
  • Choose your desired UA
  • Use the IP address or hostname of your VitalPBX along with "1000" (the extension created earlier which is the username) and the password for the 1000 extension to connect to your VitalPBX.

    You can make a test call to 17771234567, or if you are signed up for one of Callcentric's rate plans you can place a call to a traditional landline or mobile phone by dialing either:
    1 + the area code and number for calls to the US
    Or
    011 + the country code, area code, and number for calls worldwide (you may also use 00 instead of 011).
