I don't know what kind of cable you make. I am an imported cable. When you call, you will first identify yourself, then say that you are an import line and ask the customer if you can use it. If I don't use it or refuse it directly, I will apologize and hang up. If the customer uses the same type of cable, talk about the advantages of his product or ask the customer about the existing cable. If the customer really needs it, you ask for a door-to-door, and he will definitely agree. Try to make more phone calls, hehe, it will be hit at first, but our psychological endurance in doing business is stronger, and it will definitely get better in the future. Wish you success!
