I was using the phone at first be satisfied until I have found that the answering machine does not record messages at regular intervals. I noticed is that when I heard the caller leaves on the AB and I wanted to get the message later. The call was shown on the display though, the AB has the message but not recorded. Over time, I was of course approached by acquaintances who said: I will have yet spoken on the AB ....
For my mother, I bought the same device. Nor has this problem regularly. Pull out the plug from the AB and reinsert helps for a while, until the games starts from the beginning. It's annoying and has already catered for some trouble.
