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.

Keycloak OpenID Connect Integration for the Vodia PBX

Vodia’s PBX now integrates with Keycloak OpenID Connect, providing secure single sign-on for users so they can access all connected applications without repeated authentication.

Keycloak, a Cloud Native Computing Foundation project, supports standard protocols including OpenID Connect, OAuth 2.0, and SAML, offering enterprise-grade identity and access management. To ensure proper integration, Keycloak user emails must match the corresponding PBX extension emails. Complete guidance is available in the Vodia Keycloak integration guide.

Why Fax Still Matters in 2025 and How Vodia Makes It Easy

Although many consider fax outdated, it continues to play a crucial role in sectors where compliance, confidentiality, and legal proof of delivery are non-negotiable. Healthcare providers rely on fax to meet HIPAA requirements, while industries such as finance, law, and real estate depend on it for contracts and documents that require signatures or legally verifiable transmission. Unlike email, fax offers confirmation reports that serve as proof of receipt, along with time-stamped records that hold up in legal proceedings. With Vodia’s PBX, digital fax becomes faster, easier, and more accessible than ever before, enabling users to drag and drop documents, monitor transmission progress, and receive immediate confirmations.
