If you’re trying to reach the CEO, or HR Director, or VP of Operations, and the Executive Assistant takes the call, remember that he/she is your client.  She controls who you speak to, and if you treat her as the client (instead of as a blockade), she will make sure you get in.  Send her the thank-you – make the appointment with her – know her name and value her.  (This applies equally to a male EA.)  You’ll have a much higher chance of getting to the decision-maker – and many times, the EA is the decision-maker, rather than the CEO, especially regarding office management (insurance, office machines, maintenance, cleaning, etc.).  To read from another expert, check out this Forbes article:  https://www.forbes.com/sites/cherylsnappconner/2014/06/14/the-7-strategies-for-getting-past-gatekeepers/#11e005ca3606
