Aastra - MiVoice Office 400 and MiVoice MX-One / Mitel 622d v2 Firmware

« on: February 07, 2023, 08:09:18 AM »

Hello I have some  Mitel 622d V2 with the following problem. I'm not able to click the "OK" button anymore. I've seen that there is an old USB Updatetool available but I can't get the newer firmware to flash it
(When the phone boots I can hear a click .. So it should be a software problem)

Can anyone provide a link ?
