Query: Don't buy this machine

Although it comes with a lot of features, this machine [stinks]!!! The sound quality is absolutely TERRIBLE - voices are distorted and sometimes get cut off. I have to listen to the messages at least twice to figure out who called. Even though I have the machine on the lowest volume, it plays back messages quite loudly. Setting up the machine is a chore, too. Save yourself the trouble - don't buy it.
