I always got the impression that the CCT was mainly for  cross-continental communication; it's kind of implied in the name. Who's to say that Vale doesn't have a smaller, in-kingdom communication network for in-city stuff and the smaller networks connect to the CCT for anything major. So it would be like dialling an area code to get a phone in another state, or a country code to connect to another country; the smaller network is for the city itself, then they use area codes which connect you to places that may be outside the kingdom but on the same continent, and then you use a kingdom code for places on another continent.

The latter of the three would require the CCT, but you could arguably have the first and second options without having to use the CCT for them.
