Hey all, new to the forum - seeking some advice.
We have a Mitel 5000 PBX setup with about 100 5320 IP phones connected. I have a stack of new phones to setup, and I usually fire them up in the office before deployment. I'm on a POE switch (with plenty of juice, contrary to what the Mitel techs thought). Previously the phones would boot fine, but recently they get stuck with all the orange lights on, and don't boot properly.
This is pretty random, such as one in three booted fine yesterday with the other two getting stuck. Sometimes they come good after leaving them overnight on the 'stuck' mode.
Mitel wanted to upgrade our PBX firmware but I'm not convinced that will do anything because this issue seems to occur before the phones can actually try to contact the PBX.
