Hi all!
I hope this is the right forum for my question.
I have a Aastra/Mitel 620d DECT Handset with a pretty old firmware, which is too old for the PBX I want to connect to.
I already have the USB Firmware Update Tool, but I am missing a firmware package for my Handset. Searching on the Internet, I unfortunately also did not find any downloads for it.
So now my question: does anyone here have a (semi-recent) firmware package for the 620d DECT Handset for the USB Update Tool or know where I would get one?
Thanks a lot in advance!
Max
