Generally speaking, Roosh is probably right. But there isn't much harm in calling a second time. It's more of a mindset thing.
My procedure: After I get a number, call her a couple days later. For whatever reason, maybe 'cause it's college, I always get an answering machine first. I say "Hey, it's [my first name], call me back." If nothing happens for a couple days, I'll send a text. If a week or so goes by and no response, delete the number.
