Your phone call will be answered by a person who has no decision making authority. You will need to ask for someone else, and you will need whom to ask. You will also need to know which companies to call. The calling itself maybe not that complicated, but the prep work is arduous. And then you don’t start with “buy my software” you start with “Problem X is a real drag, don’t you wish it went away?”. A lot goes into it.
