Query: Don't like this at all

I own a dog daycare center and we had a difficult time hearing on a 'regular' phone. I purchased this phone in hopes that the amplification would help, it didn't. Basically the phone completely amplifies all the background noise and it made hearing the person on the other end impossible. I guess it would be good if you are just using them in your home or a quiet environment, but NOT in a place with any background noise.
