Aastra - MiVoice Office 400 and MiVoice MX-One / Downgrade Mitel 622 / 612 for older systems / SW

« on: February 13, 2019, 03:09:25 AM »

i saw a lot of posts on how to downgrade an 600 DECT phone. so i thought i do a little guide.

1: prex "esc" 2 times
2: prex the >>> key
3: type: ""***76# "
4: in the menu that appears go to "Download settings"
5: in the next menu gå to the bottom and you see "Switch to... 133.033.031" select and press ok.

Note: This software version is flawed, when starting the phone you must hold the on/off key longer than normal, wait until the phone is completely started until you release the key.
i have tested this version on old 300 system and also on even older ascotel systems. and on older SW versions of the 400 family.

Maybe think of upgrade the system?
in any case have you checked the logs if there in this cases is an error? maybe not enough voip resources in the DSP?
if not DSP resources it is often related to the firewall when you get one way audio.
