CoreSite Open Cloud Exchange + TeleFortress

Metro-Optimized, Compliance-Ready Voice Infrastructure for CoreSite Tenants

CoreSite Open Cloud Exchange + TeleFortress

CoreSite’s Open Cloud Exchange (OCX) provides secure, high-performance interconnection to cloud, network, and SaaS providers across key U.S. metros. TeleFortress connects natively into the OCX, enabling dedicated SIP trunking, STIR/SHAKEN call authentication, CLI reputation protection, and E911 routing for enterprises and platforms operating within CoreSite facilities.

“If your UC, CPaaS, or hybrid voice stack is hosted in CoreSite, TeleFortress is the trusted voice layer you’ve been missing.”
