The term gatekeeper is from 1570s, from gate + keeper. Gatekeepers serve an important role in companies to block sales people. The job of a gatekeeper is to keep sales people out so it makes sense to try and avoid them altogether. If there is no other way your best option is to simply be human and ask them for help. Counterintuitive strategies are sometimes an interesting way to win business.
