How to Interdomain Dialing on the Vodia Phone System
Published on:
July 14, 2023
Vodia gives users the ability to dial other tenants within the system using full NANPA numbers, extensions or extension alias numbers. To access this feature, a multi-tenant license is essential; it empowers you to establish multiple tenants within the system, each resolving to its designated domain. This functionality streamlines communication and fosters an interconnected network within the Vodia Phone System, ensuring efficient and flexible calling across tenants.
Vodia gives you the ability to dial across the phone system to other tenants with a full NANPA number, or with an extension or an alias number for the extension. To use this feature you will need to be running the multi-tenant license; this will enable you to create multi-tenants and have them resolve to that particular domain. For those familiar with the Vodia PBX, here's how to set it up properly.
Dial Plans
Vodia uses its dial plan to call outbound - it's usually paired with a SIP trunk but, in this case, we will use the "Loopback" mode”
Optional: You could deploy the same dial plan you already have on the system, but you will still need to create the "Loopback" in your dial plan.
If you want other users to be able to dial across domains, you will need to create the entry in the dial plan; if it's a global dial plan you can just create it there.
Assuming you already have some entry information in your dial plan, you will need to specify the preference.
Order of Operation
Your dial plan has to be clear: do you want to dial another tenant number without leaving the SIP trunk? If so, you will have to define when you want the call to terminate to a SIP trunk.
In our test, if anyone dials a tenant number, it should go to a local SIP trunk which points to the local IP; in this case it's 127.0.0.1 (see below).
As you can see, we have created a dummy number on compro.audiomercy.com on extension 4001; in this screenshot extension, 4001 from pbx.audiomercy.com calls number 781-555-6666 on pbx.compro.audiomercy.com.
Try the following:
Create a SIP trunk and rename it. Here are the settings you will need to activate:
Name to interdomain "keep it simple" ;)
Type: SIP Gateway
Global Enabled
Inter-office - Trunk settings set to yes
Dial plan for outbound calls: here you can choose any dial plan; for now we will need to create a new dial plan, so let's continue building the trunk
Registration settings
Under proxy enter 127.0.0.1
Routing/Redirection as is
Number / Call Identification
Request: URI "let the system decide" which is the default
From "Based on incoming call"
To " Same as Request - URI
Remote-Party-ID "Based on incoming call"
Everything else stays as default
Save
Dial plans
For the dial plan, you can create a new plan or use your existing one
For the Trunk: use "Try Lookback"; for the pattern use * and pattern *
You will need to go back into the SIP trunk and choose the new dial plan under the setting "Dial plan for outbound calls"
Many organizations rely on Microsoft as the foundation of their daily operations, but their communication systems often exist in parallel rather than in harmony. Vodia closes that gap by bringing telephony into the same environment where teams already work, turning separate systems into one connected structure. This approach removes friction between platforms, simplifies management, and gives IT teams better control and visibility over daily communication. It also creates a more seamless experience for employees, reduces operational overhead, and builds a stronger, more flexible foundation that supports growth, collaboration, and long-term scalability.
Vodia will be attending CVxExpo 2025 in Glendale, Arizona, from November 3–5. Sales Engineer Eric Altman will be on site to meet with current and prospective partners, demonstrating how Vodia’s PBX solutions can strengthen technology roadmaps for 2026. This year, Vodia highlights new integrations with ActiveCampaign, Freshdesk, HighLevel, Microsoft 365, Microsoft Presence, monday.com, and Odoo Cloud, along with enhanced call center capabilities such as agent activity dashboards, call recordings, and transcription features. Partners and attendees can schedule meetings with Eric to learn more about scalable, feature-rich, and cost-effective telecommunications solutions built for enterprises and SMBs.
Vodia Enterprise Call Analytics gives businesses comprehensive, real-time insights into every aspect of their call operations. Built natively into the PBX, it delivers live, color-coded dashboards, detailed call records, smart filtering, and exportable data. Enterprises can track key metrics such as answer rates, call volume, peak hours, talk times, and top performers, while also monitoring call quality through integrated MOS scoring. By turning call data into actionable intelligence, Vodia helps organizations optimize team productivity, improve customer experience, manage costs effectively, streamline workflows efficiently, and make smarter, data-driven decisions that contribute directly to revenue, operational performance, and long-term ROI.
