Query: Good solid phones, excellent audio

These are solid phones, with large buttons, well spaced. The audio quality is excellent, with callers saying you sound like you're in the same room. The batteries are NiMH, not NiCad, so they have no memory effect and last longer.There are at least eight selectable ring tones, some business-like and some more entertaining.The only drawbacks are that they are not true 5.8 GHz -- the handsets transmit back on 2.4 GHz. I have a home wireless network, and they do not interfere with it, though.And the answering machine will lose its time setting, but not messages or greeting, if the power goes out for even a few seconds.The volume controls are on the side of the handsets, so you don't have to fumble with the front of the phone while you're talking to set the volume.I would buy these phones again.
