Picture this: Your company just expanded to three new countries, but your voice termination costs have doubled, call quality is inconsistent, and you're getting warnings about compliance violations. Do you reconize that?
If you're managing telecommunications for a growing business, you know the headaches that come with wholesale voice termination. One day you're celebrating cost savings from a new international VoIP provider, and the next you're dealing with blocked calls because of anti-spoofing regulations you didn't even know existed.
Here's the reality: The global voice termination market hit $42.73 billion in 2024, but most companies are still overpaying by 30–50% simply because they don't understand how international call routing actually works.
If you're new to these concepts, our guide on what wholesale voice termination is and how it works provides essential fundamentals. Meanwhile, smart enterprises that master enterprise-grade voice termination are cutting costs by 45% while improving call quality.
This guide cuts through the technical jargon to show you exactly how international VoIP providers really work, which red flags to avoid, and how to turn voice termination from a cost center into a competitive advantage.
Ready to stop overpaying and start optimizing? Let's get practical.
The telecommunications industry is undergoing a fundamental regulatory transformation in 2025, with governments worldwide implementing stringent anti-spoofing and CLI authentication requirements that directly impact wholesale voice termination operations.
The FCC has expanded STIR/SHAKEN caller ID authentication requirements, with new third-party authentication rules taking effect in 2025. International VoIP providers must now implement comprehensive caller verification systems for all cross-border traffic, significantly impacting international call routing strategies and compliance costs.
Belgium - Royal Decree on Spoofing (2024): Since September 1, 2024, Belgium blocks all international calls presenting Belgian CLI unless they meet specific exceptions for legitimate business services. This regulation affects global voice termination providers serving European enterprises, requiring special registration for cloud-based customer support and VoIP services.
France has mandated CLI authentication for all international traffic since 2024, requiring wholesale VoIP for enterprises to implement verified caller identification systems. This impacts SIP trunking worldwide operations and increases compliance complexity for international VoIP providers.
German technical guidelines for CLI (Calling Line Identification) establish strict requirements for international carriers, with substantial penalties for CLI manipulation affecting multi-region voice termination services.
Resolution No. 777, published in April 2025, represents a regulatory milestone for Brazil, especially in combating international termination fraud and invasive telemarketing. Among the main requirements are:
🔸Mandatory implementation of the STIR/SHAKEN protocol by all voice termination providers in the country;
🔸Establishment of strict limits on call completion rates, aiming at quality and fraud reduction;
🔸Mandatory CLI authentication and real-time anti-fraud detection systems for active routes, with gradual deadlines for full implementation, scheduled for 2027, ensuring progressive compliance;
🔸Enhanced traffic transparency and traceability, bringing Brazil in line with international best practices.
These regulatory changes require Brazilian and regional operators to implement sweeping technological upgrades focused on security, reliability, and international compliance—now without the burden of requiring the 0303 prefix.
With Anatel’s new framework officially removing the 0303 dialing requirement, the regulatory priority shifts to proactive CLI authentication, STIR/SHAKEN adoption, and real-time anti-fraud detection.
This new landscape directly impacts global SIP integration strategies for enterprises throughout Latin America, reinforcing the need for advanced compliance infrastructure and automation as the industry aligns with the latest international best practices.
