Hello all. I hope all is well. I have a customer that has a uc520. All works ok, but there are several users in the office that have very soft spoken voices. When I talk into the phone, the person on the other end hears me just fine. They person on the other end reports that "it sounds like the soft spoken people are in a tunnel". I have set the max-confer x gain to "6" to try to help in this, but I dont think that has really helped any. Anyone have any other ideas that might help project the soft spoken voices?
