Finally, a resolution. I returned to site and tested the cable with my Fluke. The cable is fine. It was the volume setting for the mic and the speaker that was causing the problem. The customer said that it had not worked well since the day it was installed. The voices were garbled at best, volume low. The back doorphone is installed in a three bay delivery area serviced by tractor trailers so the background noise is quite substantial. This doesn't even include the large motors, compressors, etc (it's a anticeptic dairy packing house with tons of machinery). So I adjusted the potentiometers for both the speaker and the mike and presto, problem solved! Works great and flawlessly. The mic was turned up to the max so the background noise caused the problem. The Avaya LUADS install guide talked about that. Thanks for all of your help.
