Hungary has seen rapid growth in VoIP (Voice over Internet Protocol) adoption as businesses look for cost-effective, flexible, and feature-rich communication solutions. From startups in Budapest to enterprises in Debrecen and Szeged, companies are increasingly replacing traditional landlines with VoIP technology.
This guide will cover the best VoIP calling apps in Hungary, explain how VoIP works, compare features, share case studies, and provide practical tips to help you choose the right solution for your business.
