Hi all,
I am having challenges with Mitel 5330 IP Phone which were installed and connected to Mitel 3300 ICP , LX Controller running software rel. 9.0.
The installation is over 5 years old with over 450 IP phones (a mix of 5304, 5302, 5240, 5330 etc). All the phones have been working without problem until yesterday when all the 5330 IP phones suddenly started to display "Application Loading" continuously even after the reboot of same. The phone are working (that is calls can be made and received on the phone) but the continuous loading of application is not allowing the phones to display the user's configured programmable keys features. There was no form of system software upgrade therefore, the observed behavior of the phones (only the 5330 IP phones) is strange. Please, any idea on how to overcome this challenge? Attached is the picture of our observation.
Thank you.
