SIP trunking services provide virtual phone lines for concurrent voice/video calls, SMS, web conferencing, and more, connecting on-premise or cloud PBX systems directly to the internet. They eliminate physical lines, reduce costs (often 30-60% savings vs. legacy systems), and support advanced features like disaster recovery, toll-free routing, international calling, and AI-enhanced call management. The market thrives on digital transformation, hybrid workforces, cloud adoption, and regulatory pushes for reliable VoIP. The U.S. overwhelmingly dominates due to advanced infrastructure, major providers, high enterprise adoption, and strong hybrid/remote trends, while Canada and Mexico grow steadily from cloud strategies and digitalization/nearshoring.
