Lumen + TeleFortress

SLA-Backed Voice Infrastructure Over MPLS, Private IP, and Enterprise-Grade Access

Lumen + TeleFortress

Lumen’s nationwide network delivers enterprise-grade connectivity across Private IP, MPLS, and DIA architectures, making it a powerful backbone for secure, compliant voice delivery. When combined with TeleFortress’s SIP infrastructure, STIR/SHAKEN stack, and regulatory voice services, you get a private, deterministic voice path built for real-time communications and public sector trust.

“Lumen delivers the path. TeleFortress delivers the compliance, call trust, and voice integrity.”
