Global Carrier Services
Gaining access to the U.S. telecom ecosystem has never been more complex, or more regulated.
In today’s post-STIR/SHAKEN, Robocall Mitigation-enforced environment, international carriers are facing blocked calls, rejected interconnects, and regulatory scrutiny simply for lacking proper authentication and attestation pathways.
USTelco’s Global Carrier Services solve this problem, providing foreign carriers with trusted ingress, lawful call signing, and guaranteed termination into U.S. networks, all backed by federal compliance and Tier 1 routing integrity.
“We are the gatekeeper for compliant international voice traffic into America’s telecom infrastructure.”
