📌 Introduction
The United States is one of the most complex and competitive VoIP markets in the world. From legal compliance to real-time call routing, operating in the U.S. requires precision, power, and reliability at scale. Many switches claim to offer support for US VoIP traffic — but only a few truly deliver the performance and automation needed to thrive.
DeNovoLab’s Class 4 Fusion stands out as a purpose-built Class 4 switching platform tailored to address the exact needs of US carriers, wholesalers, call centers, and VoIP providers.
🚦 Understanding the Challenges of US VoIP Traffic
Operating in the US telecom space demands solutions that can handle:
High CPS (Calls Per Second) volumes without delay or congestion
LERG & LRN-based routing for accurate number delivery
FCC compliance for lawful routing practices
Real-time fraud prevention to protect clients and reputation
Automated billing and analytics to support transparency and efficiency
Round-the-clock uptime and support for uninterrupted services
Meeting these requirements takes more than just a VoIP switch. It takes an integrated, intelligent, and performance-driven solution.
