Is anyone else having trouble understanding a caller. I have to ask a caller to repeat themselves. It sounds like trying to hear a convesation through the speaker at a McDonald's Drive through. My business calls come across as very unprofessional. My partner puts her Blackberry on speaker so we can understand each other's conversations. I usually call them back from a land line so we can actually hold a decent conversation. I'm getting very frustrated. I've taken the phone back to Verizon twice during the 1st 30 days I owned the phone and they keep telling me to adjust the volume down. That's not working.
