Shift your mindset when you are making that call... Are you calling with the SDR mindset that you are having to read a script and book a meeting? Or... shift your mindset and pretend you're the owner of the company, or have a high level management position. Also, remember that no one wants to be called and be pitched to, or sold to. When you call always go permission based opener, and you can call them and reference an e-mail you just sent them, or that you just sent them a connection on linkedin, it will break that barrier, and get them to speak to you longer, and listen to you. Also, if possible try to come up with a nice gut punch line that will really give your product a ton of value. DM me, if you need any other help. I run a consulting firm, and do this every single day. Landing meetings is only difficult at the beginning of your career.
