Sales calls usually start with a discovery call then move to those later stages in the pipeline though, so you're just calling a sales call by another name.
Well, no, it seems your distinction is what is pedantic, as you are differentiating between discovery calls and sales calls when most would call them one and the same. This in my opinion undermines the point of your article.
I just read your other comment [0], this idea makes more sense in that you don't do any future calls, it's more like customer support in terms of helping them answer questions rather than beginning a pipeline.
