Guys,
It seems that lately we are having a lot of issues with the 69xx series phones with the combination of their Month, Week, Revision and Firmware installed.
For instance
phones made in 2018 48 with Revision: B14(03) with FW: 1.4.0.73 will upgrade, but not downgrade.
phones made in 2018 49 with Revision: B14(03) with FW: 1.4.0.73 will upgrade, but not downgrade.
phones made in 2018 48 with Revision: B16(15) FW: 1.4.0.73 will neither upgrade or downgrade.
Previous phones made in 2018 22 with Revision: 28(24), original FW: Unknown, will upgrade and downgrade, but if they have firmware 1.3.0.112 they seem to have issues.
Mitel's answer to some issues we were having on an 8.0 SP3 PR2 system was to upgrade them all to firmware 1.4.0.80 as that is the firmware that will work on a 8.0 system to resolve issues with firmware itself, but not the hardware issues the phones may have.
I also know previously if you had a phone that was below 1.0.0.148 it had to be manually upgraded to that version and then it would download the latest version from the system. This obviously is no longer a problem unless the issue of firmware updates has returned for phones issued towards the end of 2018.
So, my question is does anyone know of any other hardware/firmware/combinations that have issues?
Thanks,
TE
