Aastra - MiVoice Office 400 and MiVoice MX-One / Downgrade Mitel 622d to use it with older A300 PBX
« on: November 01, 2018, 01:54:18 PM »
Hi,

I need to downgrade a 622 dect phone to get back the original firmware.
Today the versions inside the phone are 7.0.SP8 & 7.0.SP10 (Bluetooth 3.2.1)

The older "none GAP" version is not available from the ***76# Downl. / Switch to ... menu.

Any tip how to downgrade the firmware and where to download the tool?

Regards
Verner
