Query: Please do not buy this phone

We bought this phone a little less than a year ago and it is the worst we have ever owned.-- The main issue is the very short talk time. Even when we first bought the phone after a few hours off the base the battery would die while we were talking.-- The speaker volume is quite low.-- Caller ID does not work for call waiting.-- Easy to accidentally erase messages.
