Strategies when cold calling

[Jake Burkons]

Hello Bigger Pockets,

I am currently cold calling for a wholesaling company. I often run into a recurring issue when I'm calling people and was hoping someone may have some insight or tips for me. 
When I do reach someone via phone they typically want to get off the phone quickly and are not willing to listen to my pitch. Any tips on how to approach people to get them to hear me out before hanging up.  I am open and willing to learn any and all sales tactics.

Respectfully, 

Jake Burkons
