This phone requires that you guess when to say 'hello' after picking up the receiver because of an inexplicable delay circuit. Often the caller hears some fragment of 'hello' if you guess wrong and doesn't know what's going on. You have to reset the clock every time there is a power outage. Outgoing message quality is poor. If you attempt to delete one message of a group sometimes all are erased. I can't wait to replace it - I only wish I had returned it immediately but thought I'd get used to it.
