I have a quick question for the forums:
One of our employees has left the business, and a new employee has been hired in her position. I went into CUCM, and added a new End User. I added the primary device, but it didn't seem that anything had happened. So I set his password for him, and it wouldn't work for him. It was as if the user name I set up had no ties or association to the phone. So I went into the old account associated with that phone, and looked things over and noticed that it says Primary Directory Number is still x444. So I went back into the new account, and selected 444 as primary DN for the new user, and ever since then the phone reads Ethernet Disconnected. I haven't touched the switch, in fact, the phone is PoE and is still getting powered up from the Ethernet. And I moved the phone to the Tech office here to test it where my phone is plugged in, and it reads "Ethernet Disconnected". Does anyone have a suggestion?
Have you tried a different patch cable to the phone? 802.3af is provided on a separate pair of wires than the RX/TX pairs for 10/100 Ethernet. I have seen many patch cables degrade to the point that data doesn't pass but the PoE voltage still makes it through.
