I think that is expressed as a hope for the future, and would rely on different charging systems. Difficult to see what it has to do with FOI.

I agree beginner,

Since now if you use the best value carrier you can expect to pay only 3 p for a 2 hour call at any time during the day, the time queuing on a Geographic number is now insignificant and not really a problem any longer.

In any case, in the original days of the telephone system you still had to pay by the minute if the person attending to your call went away to ask someone or to look for something to do with your conversation. Then you were paying whilst you waited, but now if you use the lowest cost providers on a Gepgraphic number you are not.
