My first ever cold calls!

I called four people today, which is four more than I have ever called out of the blue before. Zero picked up so it doesn't totally feel like an awesome use of time. (but I'm aware four is a miniscule number compared to what a lot of you are doing in a given hour, much less a whole day).

I had two lists, one of them ended up all being corporate lines (not individuals) so I didn't end up calling anyone after I realized that. Are there ways to access people's *actual* cell phones with reliability?
