Double Tapping Prospects

One thing we always run into during cold calling blocks is getting hung up on. Whether it's when you say your name, your company name, or ask for a few second of the prospects time. It's unavoidable. 

My question is though, do you double tap people who hang up on you? Immediately hit that redial button and say "Hey I think we got disconnected"? 

What is your strategy with people who hang up?

I personally double tap them. my manager and I joke about if they hang up again, to call a third time and then hang up on them.
