We have Avaya digital ports that will disable or go out of service when they have not been used in a certain (undetermined) amount of time. You can plug a phone in to merge, but have power and no dial tone… if you know the port you can bounce it,,, assign it to the phone in programming and it will activate… If you don’t know the port, you literally have to tone out the port to find it… and then bounce it… this seemed to start happening after an upgrade we had, so I feel like it may be something in the nightly routines or ?? that can be turned on or off based on customer need? I am familiar with this feature on Nortel systems, but not Avaya… can this be turned off, and if so where? Thanks for any help any one may have!
