Input: This unit not only didn't work- it stopped my home phones from working along with their caller ID. The manual didn't seem to cover the unit, this may be why l couldn't get it to work. At one point we had a message on the unit, we didn't know it was able to take messages. Tried reaching the seller about problems- no answer. We had a first generation Sentry that worked great for years- the 3.0 was junk!!
