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.

Your Outdated Phone System Is Costing Your Company Money

Legacy phone systems may still work, but they often come with hidden costs, limited scalability, and little support for hybrid work. Aging hardware, ongoing maintenance, and rigid infrastructure can quietly hold businesses back as they grow. Cloud-based VoIP systems remove these constraints by reducing telephony expenses, improving flexibility, and enabling teams to communicate seamlessly from anywhere. For many organizations, modernizing business telephony is no longer optional, it is a practical step toward efficiency and resilience.

Vodia Announces Integration with ElevenLabs Voice AI Platform

A streamlined integration connects the Vodia PBX with the ElevenLabs Voice AI Platform using a lightweight IVR JavaScript script and native SIP REFER for call transfers. Audio and call control are handled entirely through standard SIP signaling, while all conversational logic, prompts, voice selection, and routing rules are configured in the ElevenLabs dashboard. This approach removes the need for webhooks or WebSocket connections and keeps the PBX side intentionally minimal, making the deployment clean and production-ready.
