1. Complete first-time setup of Elastix

In this section, we will complete installation and initial setup of your Elastix 5 service.

  1. Once the installation has finished, you'll be prompted to choose either running the tool from the web browser or from the command line. We recommend the web browser. There is a URL provided which you will need to use to access the graphical user interface in order to configure Elastix 5.

  2. Once you've acquired the key, proceed to creating a new install and click Next.

  3. Your public IP address will automatically be detected next and you can choose to either go with the one that was detected or enter an IP address in manually. Once you've done this, click Next.

  4. Choose whether your IP address is static or dynamic. Click next.

    This is also one of the many ways an outbound caller ID can be applied within 3CX. If you choose to apply an outbound caller ID on your Outbound Route, it will be applied to all calls that proceed through this route.

Note: 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.

  • Be familiar with Telnyx's caller ID number policy

If you choose not to add an outbound caller ID on your outbound route, you can instead apply it for each user or extension.

After completing the configuration, click OK.

That's it, you've now completed the configuration of Elastix 5 Credentials Trunk and can now make and receive calls by using Telnyx as your SIP provider!
