Sweden has embraced VoIP (Voice over Internet Protocol) technology as businesses seek cost-effective, flexible, and feature-rich communication solutions. From startups in Stockholm to large enterprises in Gothenburg and Malmö, VoIP is replacing traditional landlines for better efficiency, scalability, and global connectivity.
