I have never seen this before. A little background. We recently upgraded to CM 6.3. We have installed Avaya 9408 sets. Our first issue with these was fluctuating audio which was corrected with the latest firmware download to the phones. Now I have one phone that I have added 3 expansion modules to it. About every hour or so the expansion modules will duplicate one another. The 3rd module will look like the first or the 2nd and 3rd module would look alike. I set up one on my desk and I actually saw the 3rd module all of a sudden change and now it would look like the 2nd module. I looked in the administration and it still had the original programming. But the 2nd and 3rd module on the actual phone are the same. Even if I go ahead and hit one of the SD buttons it dials the same number. Weird. Any suggestions??
