Hi all,
New to this forum & hoping I might be able to get some insight/assistance with an issue I'm experiencing at my hotel. Quick backstory on our property:
We have a Mitel MX3 III 3300 ICP (dated 2016 03) controlling approximately +/- 300 phones (5212/5312/5340).
A few weeks ago, our phone system rebooted itself without warning. Once it came back online, all of the phones began displaying a License Error message. I tried to connect to the ICP via IE as I always have before (using IE 9 emulation as the system does not seem to like any version newer than this); but, after entering my credentials on the log in page, the browser would time out while waiting and never allow me to access the menu. Our vendor was similarly unable to access the system remotely. The phones throughout the building would then start acting strangely - some would display the date/time of the reboot and never update, others would be stuck with either the "Applications Loading" message or "Please wait while updates..." screen, all while still displaying the License Error. Additionally, the guest names associated with each room via our PMS provider seem to revert back to the occupants that were in-house at the time of the original failure/reboot event.
The only way I found that I could gain access to the ICP was by removing the LAN network connection and rebooting the controller. Once it had come up fully (after 5-10 minutes) I could connect my laptop directly to the LAN port and access the User Interface (with no delay at all) in the manner mentioned above. Upon reconnecting the LAN cable from our building's core switch, the phones throughout the building would reconnect and the License Error would be cleared; but then I would experience the same time-out/unresponsiveness when trying to access the interface again. After a day or so, the License Error would return to all of the phones.
Just this morning, the ICP apparently rebooted itself again. I'm having a hard time making headway with our service vendor as they seem to only be interested in replacing our entire phone system rather than repairing our current ICP. I've been informed that our phones are no longer supported by Mitel and neither is our outdated ICP.
That's why I thought I would reach out to the professionals here for any thoughts/advice/insight. Any help would be greatly appreciated.
Thanks!
