What still exists in the cloud
A hosted PBX still has extensions and numbers. The difference is operations: you do not rack the call-control server, and seats can register from more than one building.
Callfora hosts call control for you and keeps each customer workspace on its own numbers, extensions, and history. Marketing pages describe the workspace, not the internals of the phone system.
