Query: Phone is great, answering machine is....

I have to admit, I was highly impressed with telephone capabilities of this system. There was no interference with our wireless Internet (a constant problem in our house), it was feature packed, and the color screen was very cool.However, I have never dealt with such a quirky answering machine. It would answer the first 4 or 5 calls, and then it would stop answering (even though the answering machine was turned on the entire time). It would not pick up on the next 2 or 3 telephone calls (which we checked via caller ID), and then it would work again. We returned it and exchanged for another, but still had the same problem. Very unfortunate as it was a great phone otherwise.
