Hello,
In my company we have 50 Mitel 5312 with firmware R8.0.02.01.01.01.
We have an asterisk server, firmware update works well.
Today i received 5 new phones 5312 with firmware 06.02.00.01, and when i accept the update firmware, phone show "L2 Error"and boot loop
I read on
http://www.voip-info.org : In general it is important to upgrade older firmware in sequence - eg: v3 -> V4 -> V5 -> V6 etc. without skipping any releases. Failure to do this (eg: upgrading from V3 directly to V6) may brick the phone.
Where can i found the 7.2 firmware ?
Thanks,
PS: Sorry for my bad english
