Received Sound Quality is "Tinny" and "Distorted
I recently installed a basic Ooma Telo unit in place of my old copper landline. The call quality on my end is tinny and lacking depth. It is slightly distorted. The audio sounds "over modulated". The audio is louder than it used to be on the old copper landline. It is the same on all handsets of different models. No one that I call has complained about the sound quality and when I ask, they say it sounds okay. My wife won't use the system and prefers to use her cell phone instead. Is there anything that can be done to improve the sound quality on the home end? Thank you.
