01
Inventory and design
We inventory numbers, contracts, users, devices and call scenarios. We check the network, licences and integrations.
Phone system and numbers
VoIP telephone system deployment
We design and deploy business telephone systems. We select the platform and prepare provider connectivity, numbers, devices and call handling rules. A pilot and agreed contingency arrangements come before migration and cutover.

Companies and institutions that need stable IT.
A phone system suited to your business
Changing your telephone system involves more than installing software. We establish concurrent call volume, numbers, departments, queues, hours and devices. We compare Asterisk/FreePBX, Teams Phone or another agreed platform, considering licences, the network, the provider and ongoing maintenance. We also inventory existing fax machines and analog devices; before retaining them in the new system, we check compatibility between the gateway, PBX and provider.
What a telephone system project includes
The phone system must work with your provider, network and employee tools. Related work is priced within the agreed scope.
ISO 27001 · TÜV NORD Polska
TÜV NORD Polska has certified Virtline’s information security management system to PN-EN ISO/IEC 27001:2023-08. The published certificate states its scope and validity.

We test the new system before moving business numbers. The number owner and provider agree the cutover date. During acceptance we agree emergency-call testing and correct location data with the carrier. If recording is included, the client establishes the legal basis, caller notice, retention and access before activation.
02
Build and configuration
We deploy the chosen platform, provider connection and devices. We configure numbers, queues, announcements and agreed protections.
03
Pilot and cutover
We test scenarios with selected users and test numbers. Traffic moves during an agreed window, with provider contacts and contingency instructions ready.
04
Acceptance and stabilisation
We check calls after the change, address issues and hand over documentation. We agree further support and updates.
Practical scope
What we hand over after deployment
Acceptance covers agreed numbers and scenarios, not just successful account registration with the provider.
Platform, provider, numbering, devices and integrations. We provide queue, announcement, business-hour and calling-permission settings.
Number checks, inbound and outbound calls, caller identification and call transfers. Exceptions and follow-up tasks are documented.
Account, administrator access, call restriction and supported encryption settings. We document configuration backups and the agreed contingency test.
User and administrator guidance, provider contacts and issue reporting. We agree updates, quality checks and ongoing service scope.
Number porting cannot always be reversed immediately
Before migration, we confirm documents, dates and available actions with the provider. Returning after completed porting may require a separate process. We therefore agree an alternative number or route and how employees will be informed. We do not promise an interruption-free cutover without checking the conditions.
Questions about VoIP system deployment
Can we keep our existing business numbers?
+
We confirm feasibility and timing with the provider for the actual numbers and contract. We check required documents and number ownership. The deployment plan includes porting time and tests after completion.
Do Asterisk and FreePBX mean there are no licence costs?
+
Not every feature or service is free. Add-ons, support, the provider, devices and maintenance may have costs beyond the platform itself. We define the scope and costs of each option before a decision.
What does calling through Microsoft Teams require?
+
We check Teams and Teams Phone licences and the method of connecting to the telephone network. Direct Routing requires a supported, certified SBC. Using Teams for meetings alone does not make business numbers ready to use.
How do you check call quality and security?
+
We assess the agreed path from the device through the network to the provider: delay, packet loss and behaviour under load. We review accounts, permissions and call limits. Signalling and voice encryption are checked separately; a VPN or the term VoIP does not prove that the entire call is protected.
Plan your telephone system change
Tell us the number of users, concurrent calls, current provider and target date. Explain whether numbers must stay and whether you need Teams, queues, recording or CRM integration.
