it's running with in-line power.
I'm not on-site, but the on-site data engineers claim to have:
- Replaced ALL patch cables
- Moved the patch to a different port on the Cisco POE
- Hardset the phone and Switch to 100/FULL
- Moved the patch to a different drop within the gang
- Replaced the telephone
- Reporgrammed the station in CM
- Moved the faulty telephone elsewhere in the office, put a new phone in the "mystery" office with bridged appearances...the "defective" phone worked without issue in the new location, the phone in the mystery office had the behavior re-occur.
- Ran a new drop from the comms room to the users office and certified the drop. After the new drop was installed the behavior stopped for approx. 3 days....
- We just suggested a separate power brick this morning.
Like I said...I'm still pointing the finger at the network / cabling...but since it's an Avaya phone failing, they are still kind of pointing the finger at us....
