Installing the Vodia PBX on a Microsoft Azure server provides an easy solution for businesses looking for a cloud PBX. The installation process is similar to that on any Windows operating system, but there are key steps to ensure smooth operation. First, make sure to open all necessary ports, including HTTP (80), HTTPS (443), TFTP (69), NTP (123), and LDAP (2345 for StartTLS, 2346 for TLS). Additionally, for audio traffic, virtual networks require specific endpoints with both public and private ports. The RTP range (e.g., 49900-50000 for 25 calls) must be configured based on how many calls you need. Each call uses four ports, so adjust accordingly for your system.
We recently had the opportunity to install the PBX on a Microsoft Azure server. This blog entry is about what we learned.
First if all, what is Microsoft Azure? In short, it’s Microsoft’s cloud platform. It's a growing collection of integrated services - computing, storage, data, networking, and app - that help you move faster, do more, and save money. But that’s just scratching the surface. The Vodia PBX can be easily installed on the Azure Server.
The installation of the software itself is just like installing the Vodia PBX on any other Windows operating system. Once the PBX is installed on your virtual server, you’ll have to open some ports (for example):
HTTP Port: 80
HTTPS Port: 443
TFTP Port: 69
NTP Port: 123
LDAP Port: (TCP, StartTLS): 2345
LDAP Port (TLS): 2346
RTP range: This setting will depend on how many calls you’d like to have on the system.
For the PBX to receive and send audio on your virtual server, you’ll have to open some endpoints. Virtual networks require endpoints to direct the inbound network traffic to a virtual machine. Each endpoint has a public port and a private port.
The public port is used by the Azure load balancer to listen for incoming traffic to the virtual machine from the Internet.
The private port is used by the virtual machine to listen for incoming traffic, typically destined to an application or service running on the virtual machine.
To open an endpoint on your Virtual Machine please navigate to create an Endpoint.
NOTE: An RTP range of 49900-50000 will allow you 25 calls. That’s 100 ports for RTP. Each call uses 4 ports, so you’ll have to decide how many calls you want on the system. To determine how many calls you would like on your system, multiply the number of calls by 4 to get the number of ports you’ll need.
Navigate to the Dashboard, click on ENDPOINTS, and open your RTP range here.
Vodia CEO Christian Stredicke recently joined Technology Reseller News to discuss how AI is reshaping business communications. With the release of Vodia PBX version 69.5.6, features like real-time OpenAI integration and call transcription via Whisper are setting the stage for voice-driven interactions—replacing complex phone menus with simple spoken commands. Christian emphasized Vodia’s goal of using AI to improve productivity and customer experience, while recognizing the importance of tailoring AI applications to specific industries. He likened today’s AI shift to the early days of the web, where expert guidance is key to successful adoption.
Whisper, OpenAI’s Automatic Speech Recognition system, delivers multilingual, noise-tolerant, and technical-language-ready transcription through a streamlined encoder-decoder architecture. With Vodia PBX’s integration, organizations can choose between using OpenAI’s service or hosting Whisper AI locally for complete data sovereignty and control. This on-premise option ensures that sensitive call data stays within your infrastructure while still benefiting from powerful transcription capabilities. To explore deployment options, see our Whisper AI on-premise setup documentation, review a self-hosted integration example, or follow our cloud-based call transcription guide.
Vodia is excited to attend Seatrade Cruise Global 2025, marking the event’s 40th anniversary, taking place in Miami from April 7-10. In partnership with Lufthansa Industry Solutions, Vodia will showcase the Vodia Maritime Communication Server (Vodia MCS)—a next-generation solution designed to seamlessly integrate voice, video, and messaging within cruise ship communications. Engineered for both new vessels and retrofits, the Vodia MCS enhances onboard connectivity, passenger experience, and operational efficiency, while supporting essential maritime safety and security systems. Join us at booth #3608 to discover how Vodia MCS is reshaping onboard communication in the cruise industry.
