Under the surface
The network underneath the APIs
Follow the layers from the services you use to the infrastructure we own, and choose a layer to see what sits beneath each connection.
CarrierX / Network layers01 / 03
Select a layer
01 / The services you use
Start with what you want to build.
Bring voice, messaging, and phone numbers into your application with our CPaaS APIs. Or use HD Direct for high-definition calls to and from on-net carriers.
Different ways to connect, all on the same network.
02 / The connections between networks
Go beyond the application layer.
HD Direct provides direct, on-net voice paths. For operators connecting their own networks, Carrier Exchange Transport standardizes carrier interconnection through a shared exchange environment.
CET is an interconnect offering for operators, not a prerequisite for using our APIs.
03 / The foundation we own
Built on a network we own.
CarrierX owns and operates its carrier infrastructure. Every service above this layer runs on hardware and routing we control, rather than on capacity rented from someone else.
Whichever services you choose, they run on the network we own.
A simplified view of CarrierX capabilities, not a routing diagram.
