How does a virtual PBX differ from a traditional PBX system?

A traditional PBX is a physical device installed on company premises, requiring dedicated cabling, hardware maintenance and costly upgrades. A virtual PBX runs in the cloud – the provider manages the entire infrastructure, while the company configures the system through a web panel and pays only for the channels or users actually in use. This eliminates capex costs and shortens deployment time from weeks to a single business day.

How long does migration to a virtual PBX take?

Migration time depends on the scale of the organization and the complexity of the existing infrastructure. Small companies (up to 20 users) can complete a full deployment within 1-3 business days. Larger organizations with multiple branches, CRM integrations and number porting requirements should plan for 2-6 weeks, including a parallel testing period before the final cutover.

Will there be any phone downtime during the migration?

With a well-planned migration, downtime is minimal or non-existent. The key is to run the new PBX in parallel with the existing infrastructure and carry out number porting in a time window agreed with the provider – usually outside peak hours. ACTIO carries out number porting without downtime, and the whole process is transparent to callers.

How much does a virtual PBX cost for a business?

The cost depends on the number of users, the features selected and the billing model (per user or per SIP channel). As a rough guide, the monthly subscription per user for Polish cloud solutions ranges from several dozen to over a hundred zloty, depending on the minute package and additional features. You can find an exact quote tailored to your company's needs on the ACTIO price list page or by contacting a consultant.

Is a virtual PBX compliant with GDPR?

Yes, provided the provider meets certain requirements: storing data on servers located in the European Union, offering a data processing agreement (DPA), encrypting call recordings, and ensuring access control to the admin panel. Before choosing a provider, it's worth verifying these points and requesting security documentation.

Can I keep my existing phone number when switching providers?

Yes. Transferring a number between providers – porting (LNP for landline numbers, MNP for mobile) – is legally guaranteed in Poland. ACTIO carries out porting free of charge, and the number stays active throughout the entire process. The only conditions are no outstanding balance with the current provider and submitting the request with sufficient notice.

Does a virtual PBX work for remote and mobile employees?

Yes – this is one of the key advantages of a virtual PBX over a traditional PBX system. Remote employees use a softphone on their computer or a mobile app, logging into the same PBX as their office colleagues. The internal and external number remain the same regardless of location. Solutions such as ACTIO Mobile allow a virtual business number to be assigned to a smartphone with full separation from the private number.

What features should a good virtual PBX for a B2B company have?

A good virtual PBX for a B2B company should offer at least: call queuing with configurable rules, multi-level IVR menus, call recording with archiving, conditional call forwarding (time, agent availability), CRM integration via API, real-time reporting and statistics, and support for remote work through a softphone or mobile app. AI features, such as a voicebot handling initial queries without a consultant, are an additional advantage.

Virtual PBX Migration: A Step-by-Step Guide

Moving from traditional telephony infrastructure to a virtual PBX is a decision more and more Polish companies are making – not out of trend-chasing, but for hard savings and operational needs. Yet the decision itself is only the beginning – what matters is planning the migration so it doesn't disrupt customer service or your team's work. This article walks you through the entire process: from auditing your current infrastructure, through choosing a deployment model, to the first weeks after go-live.

Why do companies migrate to a virtual PBX?

A traditional PBX built on physical hardware generates costs that many organizations don't question for years: hardware maintenance, firmware updates, dedicated cabling, and above all a lack of flexibility when changing the number of lines or office locations. A virtual PBX moves the entire call logic to the cloud – the company pays for the channels it actually uses, and configuration happens through a web panel, often within minutes.

In addition, modern VoIP voice communication enables integration with CRM systems, automation of first-contact handling through AI solutions such as a voicebot or IVR, and full scalability – both up and down – without involving your IT department.

Stage 1: Auditing your current infrastructure

What to inventory before migrating

Before taking any technical action, it's worth drawing up a list of:

the number of active internal and external numbers,
current carriers and contracts (expiry dates, notice periods),
integrations with other systems (CRM, ERP, helpdesk),
call recording and archiving requirements (GDPR, industry regulations),
user locations – head office, branches, remote work.

This step helps you avoid a situation where, after launching the new system, you discover that a specific department is missing DDI numbers or that integrating with the ticketing system requires extra work.

Keeping your existing numbers

One of the most common concerns when switching providers is losing a phone number customers have known for years. Number porting (LNP/MNP) solves this problem – you can keep your number and switch to ACTIO quickly, free of charge and without downtime. The entire process runs in the background, and the number's unavailability window is minimized to an absolute minimum.

Stage 2: Choosing a deployment model

Public cloud vs. a hybrid solution

A pure-cloud virtual PBX is the fastest deployment path – no hardware investment, and full provider responsibility for infrastructure and SLA. For companies that, for various reasons (regulations, security policy), want to keep part of their infrastructure on-premise, a good alternative is 3CX Phone System – a solution that can be deployed either in a private cloud or on your own servers, keeping full control over your data.

Companies with a high volume of outbound calls, or those requiring dedicated SIP channels, should consider supplementing their PBX with a SIP Trunk, which provides fixed capacity and a predictable cost per channel, regardless of the number of simultaneous calls.

Number of users and the licensing model

Virtual PBX systems are most often billed per user or per channel. Before signing a contract, it's worth carefully reviewing the price list and comparing the real total cost of ownership (TCO) against your current phone expenses. In most cases, companies with 10 to 200 employees achieve a return on investment within 6-18 months.

Stage 3: Planning and configuration

Call flow and IVR

Before you technically launch the new PBX, sketch out the call flow: what IVR menu a calling customer should hear, which queues calls should land in during business hours, and what should happen outside them. A well-designed call forwarding setup and automated menu shortens handling time and reduces the number of missed calls.

If your company handles a large volume of inbound traffic, it's worth considering a voicebot or intelligent IVR at the planning stage – AI solutions can independently handle 20 to 40% of typical queries, taking the load off your consultants.

Integration with business tools

A modern virtual PBX should communicate with your CRM or helpdesk system. Typical integrations include displaying a customer card on an inbound call, automatically logging calls, and click-to-call directly from the CRM interface. If you're also planning SMS campaigns, it's worth setting up SMS via VoIP during deployment, or using a ready-made SMS API for more advanced automation scenarios.

Stage 4: Testing and go-live

A test environment before production

The safest strategy is to run the new PBX in parallel with your current infrastructure for 2-4 weeks. During this time you can test call quality, verify that all forwarding rules work, and train employees without risking any interruption to customer service.

Mobile or remote employees can use ACTIO Mobile – an app that assigns a virtual VoIP mobile number to a smartphone, keeping full separation between the business and private number.

Pre-go-live checklist

Porting of all numbers completed or scheduled with a cutover date
IVR and queue configuration verified in the test environment
Employees trained in using the softphone or new IP phones
Call recording configured in line with GDPR requirements
Voicemail and out-of-hours announcements recorded and active
Provider's service contact known to the entire IT team

Stage 5: The first weeks after migration

Quality monitoring and optimization

After going live, monitor call reports for the first two weeks: number of missed calls, average queue wait time, peak hours. This data will let you quickly identify whether the IVR flow needs adjusting or whether you need additional agents at specific times of day.

If you have doubts about the optimal configuration or want to discuss your organization's specific requirements, talk to an ACTIO consultant – a free needs analysis helps avoid costly mistakes at the deployment stage.

Security and GDPR compliance

A virtual PBX processes personal data – phone numbers, call recordings, call logs. When choosing a provider, make sure that:

data is stored on servers located in the EU,
the provider offers a data processing agreement (DPA),
recordings are encrypted at rest and in transit,
access to the admin panel is secured with two-factor authentication (2FA).

As a provider with 25 years of experience, ACTIO serves clients in regulated sectors – energy, transport and retail – where security and auditability requirements are especially high.
