VoIP and Cloudflare

Published on:

July 20, 2022

Cloudflare is a service that enhances security and performance by masking your web server's IP. For users of the Vodia multi-tenant PBX, however, masking the DNS IP can cause issues during phone registration. While the phone can initially provision via HTTP, it won't register because the masked DNS IP blocks communication. To resolve this, you need to disable the Cloudflare proxy for your DNS, allowing the phone to register correctly. Find out how to get your phone registered by adjusting these settings in your Cloudflare account.

What is Cloudflare? Cloudflare services are used to increase the security and performance of your website.  It does this by basically masking the IP of your DNS to your Web server. If you are using a DNS on the Vodia multi-tenant PBX, then it would not make sense to mask the DNS IP when using Cloudflare. The initial provisioning of the phone is done through HTTP, which will work to get the phone’s config file; whenever the phone is ready for registration, however, the phone won't be able to register, since the DNS IP address is masked (this renders the phone unusable).  

Follow these steps to get your phone registered:

Navigate to your Cloudflare user portal, click on your domain, then on DNS. Check your DNS management and change the proxy to use DNS.
