There are no logs on the 3650 phone POE switch indicating any issues. Since the switch doesn’t indicate any problem, and the issue doesn’t always happen at the same time (could be 3pm or 12 pm for example), it’s extremely difficult to troubleshoot and narrow down the problem. Does anyone have any suggestions on how to figure out what is causing this issue?
