I think the biggest challenge when you're selling over the phone is that you're unable to make that face-to-face contact, to be able to read the body language, to pick up on their facial expressions, their body language. In person, the advantages you do get to see them face to face and you are able to pick up on their body language and their expressions and kind of what they're feeling when you're speaking to them. The best way I believe to overcome those challenges is to be a good listener, listen to what the root cause is for the objection, and then offer a solution to those objections.
