CENCEN Area Code
A unique three-digit code identifies each CEN Network. Combine it with the existing seven-digit Local Number: 214 + 3151234 = 2143151234.
One federation. Independent networks.
CEN connects Member Networks without replacing their existing PBX infrastructure.
Member Routing API
CEN returns the member’s Routing API and Local Number. The member decides how to resolve its own Local Blocks, extensions and final PBX destinations.
PSTN isolation
Use the local access prefix 88 before the Global CEN Number. Ordinary 10- and 11-digit PSTN numbers, emergency numbers and local extensions keep their existing routes.
