Now that I think about it, given that it's 2014 and smartphones are ubiquitous and free calls are the norm and so forth, it's amazing that there isn't a standard screen that pops up before making any paid call asking to confirm the cost. "Calling this number will cost $3/minute. Do you wish to proceed?"
Of course, such a thing could only cost carriers revenue, so why would they ever do it....
In the mobile domain (under the 3GPP standard), there is something called "Advice of Charge" that would give such functionality but most carriers do not deploy it unless local regulations demand it.
