Getting Started with 3CX

Thank you for downloading and installing 3CX!

Using the wizard, you have now configured the basics of the PBX, however there are still a few steps you need to follow to make your first call.

1. Configure your IP Phones

In the wizard, you created a few extensions. You now need to use those extension numbers and passwords and enter them in your IP phones. If you do not have any IP phones, you can use the 3CX VoIP phone instead. You can use the 3CX client for Windows, which can be downloaded here.

You can find a list of supported IP phones, with detailed configuration guides within our Support page.

2. Configure a VoIP Gateway or VoIP provider

After you have configured your IP phones, you need to configure a gateway or a provider to make external calls. A VoIP Gateway allows you to continue using your existing phones lines. Alternatively, you can sign up with a VoIP provider and use this for external calls.

You can find a list of supported VoIP Gateways, with detailed configuration guides within our Support page.

A list of supported VoIP providers can be found here.
