Is this for cold-calling, or an actual salesperson that is on the ground? It's a little unclear.
Love the idea. Definitely will work for some industries.
Doesn't matter what you think it means - if it confuses everyone, just change it.
It may seem archaic here, but it is standard terminology in sales to refer to a physical stop-in as a 'call'.
Door-to-door-salesmen-as-a-service sounds a whole lot more impactful that cold calls over the phone. which could theoretically even be off-shored as well as outsourced.
