We have a customer with an Axxess running 5.342 on a 512CPU. They have two receptionists, each with two DSS units. The DSS units buttons (of extensions in DND) flash in a strange pulse from DSS unit one to unit two at the same attendent. This pulsing happens at both receptionists. When system resets due to programming changes, etc, the DSS units start to flash together again, and that lasts a few days. Similar experiences and/or ideas?
