Query: Did not deliver on promises

I purchased this phone with high expectations based off product features especially the auto attendant. We purchased 2 each 944 and 2 eacch 964. This was for a small office (2 people) The 944 phones worked together but the 964 phones did not. The manual was the worst to date I have read on a phone system and gave no detail. After countless hours with support staff on phone (email support was a joke they copied sections from manual and sent them to me even though I had described following every step of the manual to them in detail) it was determined that while they advertised it would work with any anaolg line system it would not work ours because our system had been upgraded by BellSouth. During course of events I found out that it was common for the phones not to work together. The system never worked as promised and phone manufacture gave up trying to solve problem.
