Ireland has rapidly embraced VoIP (Voice over Internet Protocol) technology as businesses seek cost-effective, flexible, and feature-rich communication solutions. From Dublin startups to multinational firms in Cork and Galway, VoIP is replacing traditional landlines to improve efficiency and international connectivity.
