Poland has rapidly adopted VoIP (Voice over Internet Protocol) technology as businesses seek cost-effective, flexible, and feature-rich communication solutions. From startups in Warsaw to enterprises in Kraków and Wrocław, VoIP is replacing traditional landlines to improve efficiency, scalability, and international connectivity.
