I have a Premier ESPDX, 1 cabinet, that I work on. It has alot of the 8D EVT phones installed
mostly two to a circuit. Lately I've been having
problems with phones starting to motorboat (data
noise). Ive tried repunching the connections, new
line cords but I usually can only fix them by switching to a different port. Some of these phones have been working fine for years and now
are having problems. Am I missing something or is the system just getting old?
