Using the Vodia PBX in large organizations

The telephone system for the modern enterprise

Having staff members work from home as well as from the office creates new challenges for enterprise IT departments. The Vodia PBX can address the challenges by supporting multiple network interfaces, so that calls in the office are routed through a different network than those who work from home. This makes the usage of VPN optional, but not mandatory. Especially for users that need to use private cell phones that dramatically simplifies the rollout.
In order to address work-life balance and user acceptance, the organization can set up working hours. Outside of these hours, the system will not call mobile users. Small in-house call centers benefit from the Vodia PBX queue feature set, so that there is no need to use external software for those groups.
The Vodia integrations framework can be used to connect to standard third party software but also internal servers, for example to look up callers on inbound calls of to log call activity after a call disconnected.

Not being bound to a specific SIP trunk provider is important for most businesses. Connect the Vodia PBX to the public telephone network through preconfigured SIP trunks or create your own SIP trunk connection. Check out our list of SIP trunk providers for the most popular providers.

Integration into business processes

Integration framework

Integrations make all the difference when it comes to workflow efficiency. Our integration framework comes with predefined popular integrations, but if you like you can integrate your own business software with the Vodia PBX.

Reporting subsystem

Advanced system analytics

Reporting critical numbers is key for a smooth 24/7 operation of any business software. You may monitor the PBX through its built-in SNMP server or have it send emails at the end of every day. When something important happens, the system administrator may receive an email with details.

Appearance customization

Branding support

The default branding in emails and web access can be easily changed through the administrator web portal. If needed even deeper changes can be done with almost every aspect of the user interaction. And of course audio can be changed so the callers get the familiar appearance when calling in.

Easy to run in-house

Whether you aim to run your telephone system in your own rack, your private cloud, public cloud or in the LAN, the Vodia PBX comes with the flexibility that addresses even the most complex setup scenarios for a stable operation—still easy enough to be run. Choose your favorite operating systems, including Windows and Linux.

It just takes one server

Even though the Vodia PBX comes with numerous features, that does not mean you need a server farm to run it.The PBX runs on a single instance. This dramatically reduces the complexity for running it. You can even choose your favorite operation system. And if you are using virtual machines, you will like the fact that you can easily run the Vodia PBX like most other virtual machines, including automatic snapshots and failover within seconds. This dramatically reduces operational costs and provides the uptime requirements of modern enterprise.

Full control over your data

The cloud can be challenging when you want to know where your data is and who has access. Because the Vodia PBX runs on a single instance and you decide to run it now your own, that is where all the data is as well. This dramatically reduces the complexity for data storage, which helps not only with compliance requirements but also with the desire of management to know where data is being stored and who has access.
You don't have to deal with hosted services that send every call to an AI robot for analytics or store all metadata in their own databases. Of course every call on the Vodia PBX can be encrypted using standard SRTP encryption. It is entirely up to the administrator of the PBX to decide who will be able to access communication.


Public cloud

Pick whatever tickles your fancy: AWS, Azure, Google Cloud and many more that offer Linux or Windows in the cloud. We even have a ready-to-go Digital Ocean instance that saves you the minute or two it takes to install the PBX.


Private cloud

Deploy the system to your local system and keep all the data in-house. It can be run on standard servers, physical or virtual. Setting up the PBX service means just running  another service in your rack.


Ready to use hardware

If there are a lot of branch offices in the company, consider deploying Vodia IO or IOP in the remote locations. They can be still managed through the same web interface like the big systems, which reduces the training requirements in the company.

PBX with no limitations

Keep the infrastructure

Just because you are changing PBX doesn't mean the whole system that has been in place and working seamlessly has to go. Vodia PBX offers all the possible deployments and hosting solutions. From your own datacenter to a pocket sized Raspberry PI, from AWS to a low-cost Digital Ocean instance.
Windows®, macOS®, Linux distribution — we have ready to go implementations that only take a few clicks. Looking for an update? The PBX can be updated in seconds without the need for server reboots.
Our always expanding suite of features will intrigue even veterans of the telecom industry.

Work from any where

Whether you aim to run your telephone system in your own private cloud, public cloud or in the LAN, the Vodia PBX comes with the flexibility that addresses even the most complex setup scenarios for a stable operation. The Vodia PBX grew up in environment where users where accessing the service from LAN, WAN, VPN, VLAN, IPv4,  IPv6, all mixed up.

Session Border Controller

One way to make the PBX available to users from any location is to run it on a public IP address. A session border controller (SBC) is a necessary component for operating a telephony service in the cloud. Vodia had its own SBC from the beginning, and that has grown into a core component of the PBX.


What you see is what you get—Vodia PBX provides many ways to monitor what is going on. Either by simple SNMP reports or by daily admin emails, the system administrators are being informed about the health status of the service. And if something special happens, the PBX can send a email or SMS to the admins and let them know about it.


The SBC in the Vodia PBX handles all necessary encryption algorithms for secure communication. The Vodia PBX terminates WebRTC traffic natively. This makes it possible to call internally from WebRTC-based clients such as the web browser or the Android app to standard VoIP phones. It comes with built-in support for the Let’s Encrypt® service, which makes it easy and fast to obtain the necessary certificates.

NAT traversal

When operated on a public IP address, the PBX automatically detects that a device is located behind a firewall and adjusts the routing to that destination accordingly. This is important for users that work from home and for users that are using the iOS or Android app. There is no need to use a STUN server, so that will dramatically reduce the installation complexity.


Most businesses require much more than one person speaking with another. The Vodia PBX offers a number of options for handling calls between multiple parties. Our PBX not only offers the best possible experience to callers, it also helps you get things done fast - and with a personal touch.

WebRTC Technology

The Vodia apps are taking full advantage of WebRTC. This includes the OPUS codec for excellent audio quality and DTLS security context negotiation.

User-Defined Redirection

Finding a user is one of the most important tasks that the PBX has to fulfill. A missed call is wasted time for the caller, a waste of productive time and must be avoided as much as possible. The PBX supports several ways to find a user, where ever the user is. The user can program various redirection options. A simple "Do not disturb" (DND) redirects calls either to coworkers, offers callbacks after DND is disabled or just sends calls to the users mailbox. Redirection on busy, timeout or just always allows explicit programming of the redirection target.

User Portal Call Controls

User portal provides easy call control, like making, ending, transferring, holding etc. for multiple calls both through WebRTC or desktop phone associated with portal. Also gives live status of other users' phones.

Trunk Reporting

Because trunks are essential resources in the PBX and sometimes Internet connections can be challenging, the PBX can send emails when the registration status changes on a SIP registration trunk. This is very useful when troubleshooting random behavior with SIP termination. As with the extensions, SIP trunks can also trigger the recording of the calls that are handled by the SIP trunk. This feature is very useful to troubleshoot problems with SIP trunk providers and is welcome material to the support staff.

The First Impression

When the calls hits the auto attendant, you can have the system play a customized message to greet your callers. The system will establish a simple dialog with the caller, using prerecorded and your own recordings. The caller can also select the language from the auto attendant. The announcement for the language selection is made in the to-be selected language, so that the caller can actually understand it.

Reporting Emergency Calls

In environments where guests, patients or residents need to be able to call emergency numbers, it is valuable and sometimes legally required that frontend staff gets a notification about the call and its location. The PBX can send emails, SMS and initiate overhead paging in such a case and streamline the handling of emergencies.

Ringback Tones

Ringback tones can be set per hunt group; for example, to mix ringback tones with announcements which provide additional information to callers.

Record Emergency Calls

While other calls may be recorded or not, emergency calls are special. Because of their special nature, emergency calls can explicitly be recorded or explicitly not be recorded.

Real-Time ACD Reporting

The agents and selected management accounts can use their web browser to monitor the calls that are waiting and connected. A brief summary shows how much time agents have spent on the phone and idle; the web page also contains information about the number of processed calls, the average and total call duration and how long callers had to wait on average before the call got connected to an agent.

Rate Tracking

Trunks may have rates that define how much a call to a specific destination will cost. Those rates depend on the starting pattern of the destination. Inbound calls can also be billed depending on the number that was dialed, making it possible to show the cost for toll-free numbers. VoIP phones that support advice of charge (AoC) can show the cost on the display while the call is progressing. The cost for the calls can be fed into a monthly bill using a cloud-based billing platform. Rates can then include semi-flat rates, where users get a budget of monthly included minutes.

Queue Call Limit

The maximum number of calls for the queue can be defined to ensure that limited trunk resources are not overloaded. When that number has been reached, the ACD can send a busy signal to the caller, so that the trunk line gets cleared up. This feature is important when other trunks lines need to be kept open for other high-priority queues or for other services.

PSTN Gateway Setup

Similar to the automatic provisioning of VoIP phones, the PBX can also automatically set up PSTN gateways with a reasonable configuration. For this the administrator needs to provide the IP address of the device (typically a statically assigned IP address) and make sure that the device is using its default username and password. After the initial configuration, the PBX will set up a dial plan for the new trunk. The administrator can use this plan as a template to build onto with more elaborate rules for dialing out.

Prerecorded Announcements

There is a number of prerecorded announcements available that you can use to send calls to the accounting department, sales, support, the front desk, medical services and many other destinations. Those can be mixed with your own recordings. If you like, you can have the PBX mix the prompts with music on hold-sources.

Predefined Trunk Providers

Vodia maintains a list of known SIP trunk providers. Those providers can usually be configured by just providing the username and the password. After setting up the trunk, the PBX will register to the right destination and set up the SIP headers the way the SIP provider wants it. There is no further tweaking of the SIP settings necessary, which makes it easy to use SIP trunks.

Personal Address Book

Each extension has it own address books. Extensions also share the domain address book, which is available for the whole domain. The PBX address book stores information in the PBX itself. Users can edit the address book through the web interface. The address book entry may also tell the PBX to reject calls from the contact

Outbound Call List

When agents place outbound calls, the PBX can associate the caller-ID of the ACD with the call and log the call in the statistics for the ACD. Each ACD keeps a list of numbers that should be called. This list can be uploaded through the web interface. The agent can pick the next number from the list by dialing a star code. If the call connects successfully, the agent can use the "pound" key to take the number off the list; if the call was not successfully connected, the agent may put the number to the back of the list, so that the agent or someone else can try to call this number later. This feature is also available from the users cell phone, enabling mobile outbound calling. Because of the simple next-function for outbound calling, it is easy to use this function from regular cell phones.
