Hello Fellow Mitel Techs,
I have a Mitel UC360 running 2.1.3.13. That is experiencing call dropping, which happens intermittently. This unit has been replaced once due to the logs showing an exuberant amount of "401 - Unauthorized" & "Setting Network Loss Icon ON/OFF!!!!" messages. (See Example Below)
08-31 08:49:16.553 1426 2062 W vcs : IUA >> Event Mgr: User-Id[0] REGISTRATION FAILURE
08-31 08:49:16.553 1426 2062 W vcs : IUA >> Event Mgr: REGISTRATION FAILURE Status Code:[401]
08-31 08:49:49.357 1610 1610 W StatusBarPolicy: Setting network loss icon ON!!!!
08-31 08:49:53.365 1610 1610 W StatusBarPolicy: Setting network loss icon OFF!!!!
Upon seeing these messages were we're originally thinking that perhaps the Ethernet port on the UC360 was going bad, then made the decision to have it swapped out and RMA'd with Mitel. After the deployment of the new UC360 all seemed well for a couple weeks and then the customer reports the dropped calls are back. Typically the call drops happens about 30-35 minutes after the call starts.
I looked in the logs again and see the same thing. I then realized that this UC360 is also doing some LDAP to have the corporate directory synced, this is maybe where the 401's are coming from, but from what I can tell is that it should only sync based on a schedule that I have configured (Every Friday at 5:00pm). Can someone tell me what the "IUA" means in the log message? I'm kinda at a loss here.
Any help is greatly appreciated!
Thanks,
