Integrating Prometheus with Vodia PBX enables effective monitoring of your phone system’s performance. Start by creating an API account on Vodia PBX to grant access to Prometheus, followed by the installation of Prometheus on DigitalOcean. Update the prometheus.yml file to include your PBX as a target by configuring the DNS, username, and password. Explore the Vodia API for available system stats, such as CPU usage and memory. Finally, create custom stat panels in Prometheus to visualize and track these key performance metrics in real time.
Prometheus is an open-source monitoring and alerting toolkit that is part of the Cloud Native Computing Foundation. By integrating it with Vodia PBX, you can effectively monitor and manage your phone system's performance. Here’s how to get started:
Step 1: Create an API Account on Vodia PBX
To allow Prometheus to access Vodia PBX data, you need to create an API account. Follow these steps:
Log in to Vodia PBX as an Administrator:
Navigate to the system level where you can manage user accounts.
Create a New User Account for API Access:
Go to the Administrator section.
Create a new account with the following details:
Account: Choose a user name.
API Access: Enable API access.
Type: Set the account type to Regular.
Password: Set a strong, secret password.
Save the Configuration:
Save the user account configuration.
Keep the username and password handy, as you will need them for Prometheus to access Vodia PBX data.
Once your server is set up, you can access the Prometheus user interface by going to http://your_server_ip:9090/
Setting up the .yml file
By default, Prometheus is set up to monitor itself and Node Exporter. To monitor more systems, you need to update the configuration file located at: /etc/prometheus/prometheus.yml
3 things need to be changed in the Prometheus .yml file config file
targets: ['123.vodia.com'] Here is where you will set the target - in this case it will be your PBX DNS name
username: 'prometheus'
password: 'prometheus'
Note: Do not remove the ' ' and [ ] in the config file leave it as is and change the value
Once you have edited the config file, you can modify the prometheus.yml using nano or any edit you desire by copy-pasting the config or simply creating a new .yml file and renaming the old file.
Restart the service by sudo systemctl restart prometheus
Check the Prometheus and click on System Stats - this will show all of the available APIs for Prometheus, and you will see an Example Response. Click on "view more" and it should look like this:

# HELP system_memory_all Total # TYPE system_memory_all gauge system_memory_all 172928 1719852690061
Creating a stat panel on Prometheus
Click "add panel" and enter the Vodia API cmd - in this case system_cpu_srv_max, then press execute: you can create many panels to monitor the PBX.
Join Vodia Networks on April 8 for a live, in-depth webinar on how real-time media streaming is powering the future of voice communication. Discover how Vodia PBX version 69.5.6 enables seamless AI integration, live call transcription using the Whisper API, and secure voice data handling. Hosted by Sales Engineer Eric Altman and VoIP Engineer Hamlet Collado, this session will walk you through real-world use cases, including OpenAI and Google Speech-to-Text integrations, MS Teams support, and new security features. You’ll also get a first look at Vodia’s AI roadmap and have the opportunity to ask your questions during a live Q&A.
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 Sales Engineer Eric Altman attended Enterprise Connect 2025 on March 18 and 19, where he connected with partners and gained insight into the future of enterprise communications. AI was the clear focus of the event, with discussions centered on agentic systems, chatbots, and generative technologies. “It was certainly the main element in the atmosphere,” Eric noted. He also shared his excitement about Vodia PBX version 69.5.6, which includes real-time AI integration with OpenAI and call transcription using the Whisper API. The event confirmed that AI is rapidly becoming a core component of modern communication platforms—and Vodia is well-positioned to lead the way.
