Published on:

March 17, 2025

Vodia PBX is built with security at its core, featuring a codebase that eliminates third-party vulnerabilities. Passkey authentication, IP address locking, and multi-factor authentication (2FA & SSO) protect against unauthorized access and credential theft. Advanced rate limiting defends against SIP attacks, while SIP TLS and WebRTC encryption secure VoIP traffic. Automatic SSL certificates and secure MAC-based phone provisioning enhance data protection. With a distributed architecture for scalability and comprehensive toll fraud prevention, Vodia PBX ensures reliable, secure, and seamless communications.

In today's interconnected world, security isn't a luxury; it's a necessity. Vodia PBX is designed with a security-first philosophy, ensuring your communications are protected from the ground up. Unlike systems reliant on potentially vulnerable open-source components, Vodia's codebase is meticulously crafted and managed by our in-house team. This eliminates reliance on external dependencies and provides a robust foundation for secure communications.

We go beyond basic security measures, offering advanced features that empower you to proactively defend against data breaches and toll fraud. Passkey authentication, leveraging the power of public key cryptography, provides a seamless and highly secure login experience, eliminating the risk of stolen credentials. Furthermore, system and domain administrators can be locked down to specific IP addresses, significantly reducing the potential for unauthorized access and bolstering your overall security posture.

Key Security Highlights - Building a Shield Against Vulnerabilities

  • Proprietary Codebase - A Foundation of Trust: Vodia's in-house development ensures a secure, reliable, and consistently updated platform. By maintaining control over our codebase, we eliminate the risks associated with third-party vulnerabilities, providing you with peace of mind.
  • Passkey Authentication - Passwordless Security for the Modern Era: Embrace the future of secure logins with passkeys. Utilizing public key cryptography, passkeys eliminate the need for traditional passwords, effectively preventing credential theft and offering a frictionless user experience through biometric authentication.
  • IP Address Locking - Granular Control for Enhanced Protection: Restrict administrator access to designated IP addresses, creating a fortified perimeter around your PBX. This precise control significantly reduces the attack surface and minimizes the risk of unauthorized entry, ensuring only authorized personnel can manage your system.

Enhanced security is further achieved by the ability to utilize alternate SIP ports, and Vodia's auto-provisioning ensures seamless phone configuration.
  • Automatic SSL Certificates - Securing Web Traffic: Vodia's built-in Let's Encrypt integration automatically generates SSL certificates for new tenants, ensuring secure HTTPS web traffic and protecting sensitive data.
  • Secure Phone Provisioning - MAC Address Control: Vodia provides secure MAC-based phone provisioning, allowing administrators to authorize specific devices for configuration downloads within a defined timeframe. The PBX automatically generates strong SIP and web interface passwords, eliminating the need for manual configuration and enhancing security.
  • Distributed Architecture - Scalability and Redundancy: For large-scale deployments, Vodia enables a distributed architecture, allowing you to distribute extensions across multiple servers, data centers, or regions. This approach enhances scalability, redundancy, and performance, ensuring your communications infrastructure can handle growth and maintain reliability.
  • Comprehensive Toll Fraud Prevention: Vodia offers a suite of features to protect against toll fraud, including: 
    • Limiting registrations per extension. 
    • Controlling call volume per tenant or SIP trunk.

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.

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.
