Challenges I often run into are a lack of ability to express facially over the phone. I believe interacting through facial expressions are a crucial way of communication. It's how we build trust a lot of the time. It's how we, you know, kind of communicate things that we don't know how to communicate and it can be difficult to read someone when it's just their voice. I've overcome those things by trying to find similar tics in vocal responses and interactions and present similar vocal tics in communications and responses. In person, the challenges are, of course, minimal comparatively. But in person, for the most part, I find challenges when the person doesn't believe that the product that we're offering is necessary and not in the budget. Those may be things that are hard to shake for the customer.
