In Belgium, businesses and individuals are increasingly turning to VoIP calling apps to replace traditional phone lines. Whether you’re running a startup in Brussels, a remote team in Antwerp, or managing customer support in Ghent, choosing the right VoIP app can save money, improve communication, and streamline operations.
VoIP, or Voice over Internet Protocol, lets you make voice and video calls using the internet instead of landlines. With Belgium’s high-speed broadband infrastructure and growing remote workforce, VoIP adoption is accelerating rapidly.
This guide covers everything: how VoIP works, top apps available in Belgium, pricing, pros and cons, setup tips, and recommendations for personal and business use.
What is a VoIP Calling App?
A VoIP calling app converts your voice into digital data packets and transmits them over the internet. Unlike traditional phone lines, VoIP does not rely on PSTN networks.
Benefits include:
- Lower call costs for domestic and international calls
- Flexibility to use mobile, desktop, or tablet devices
- Features like call recording, voicemail-to-email, and video calls
Popular apps in Belgium include RingCentral, 8×8, Zoom Phone, NFON, Aircall, and MyNetFone Belgium.
How Does VoIP Work in Belgium?
The process is simple:
- Speak into your device’s microphone.
- Your voice is converted into digital packets.
- Packets are transmitted over broadband (fiber, DSL, or 4G/5G).
- The recipient’s device reassembles packets into voice.
Belgium has a reliable broadband network. Fiber-to-the-home (FTTH) coverage is expanding, particularly in Brussels and Antwerp, which ensures high-quality VoIP calls with minimal latency.
Key compliance considerations:
- Data hosting and GDPR: Ensure the app hosts data in Belgium/EU for privacy compliance.
- Number provisioning: For a Belgian number (+32), the VoIP provider must adhere to local telecom regulations.
