David Werdiger likes challenging trends when it comes to call rates, observing simple trends in the number of calls people make, and reflects on why people do not think as much about the cost of the calls, so they make more of them.
“I like nothing more than mining through the millions of CDRs that we collect and process on behalf of our Partners (actually, I do like more than that, but some things are beyond the scope of this blog). It’s like playing a jigsaw puzzle – sorting through lots of small pieces of information to discover a bigger picture. here are a few fairly simple trends that I have observed. Call rates continue to trend down, but this is more than made up for by the increase in usage, i.e. the number of calls people make”. [Billing Bureau]
