The Vodia PBX integrates with the Google Translate API to transcribe voicemail recordings into text; this text is then included in voicemail notification emails. To enable this feature, you’ll need a Google Cloud account, along with an active Voice API subscription key - this can be created under “APIs & Services” in the Google Cloud Console. This API key, which should be restricted for security, is entered into the Vodia PBX system to activate transcription capabilities. For multi-tenant setups, voicemail transcription can be managed per domain or disabled for specific extensions, offering flexible control over API usage.
Google offers a powerful API for converting speech into text. The Vodia PBX is currently using this feature to convert voicemail recordings into text format; it includes that text in the voicemail notification, which is typically sent to the user by email. This API must be enabled in the Google Cloud Console.
After you have set up an account with Google Cloud, make sure you provide your credit card information so you can enable the Voice API. You will also have to create a project that holds the API key. You can do this in “APIs & Services” in the Dashboard area.
Activating Google Cloud Subscription Key
After you have created a project, you need to navigate to the “Credentials” area, where you can create new credentials for your project. You need to create a new API Key.
You should then restrict the key by some means (e.g., by limiting it to your server IP address) so nobody else can use that key unless it's used from that IP address.
Enable Voicemail Transcription in Vodia PBX
After you have set up your account on the Google console, copy the API Key into the PBX in admin mode, General/Settings/Notifications. There you can also determine if domains should have the feature enabled or not, unless you set it explicitly in the domain settings.
Multi-Tenant Scenario
In some cases, you would want to disable the Google API per extension. To disable, go the main page of your domain page and click on the edit button, scroll down to "Enable voicemail to text API" and switch it to off.
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.
Multi-tenant architecture allows MSPs to manage multiple customers efficiently on a single, secure PBX while maintaining strict tenant isolation. By sharing infrastructure, MSPs can reduce operational costs, apply updates and security patches centrally, scale customers on demand, and onboard faster without increasing complexity. As cloud and SaaS models continue to dominate, a well-designed multi-tenant phone system provides the control, flexibility, and reliability MSPs need to support growth, evolving requirements, and modern communications workloads.
A flexible, cloud-neutral PBX built for real-world deployments in 2026, Vodia supports MSPs, enterprises, and service providers with an open, SIP-compliant platform designed for scale. With Vodia PBX version 70 arriving in Q1 2026, the platform brings multi-tenant hosting, reuse of existing IP phones through centralized provisioning, built-in WebRTC softphones, transparent licensing, and partner-driven support, giving organizations full control over modern business telephony without lock-in or hidden costs.
