I am a hotel lobby product and need to sell it to customers. How should I communicate with customers by phone?

The core of sales is to meet each other's needs with their own products and services.

You should try your best to understand each other's dissatisfaction with the existing products. You can investigate from the customers of the other hotel first. Hotels will attach great importance to customers' opinions and grasp each other's needs. Then, when communicating with each other, highlight the advantages and applicability of your products. As long as we can solve each other's problems, communication is easy.
