Panasonic KX-NT551/553 latest firmwares needed

(OP)
Hi,
I'm desperately in need of latest firmware files to update my NT551, NT553 and NT343 ip phones.
I have many phones bought in many years with different versions delivered and there are some stability issues with older versions.

I really appreciate your help if you have the original firmware files available and share them with me.

I pushed all files and found out I miss firmware for NT-321 and NT-546 phones.
Do you have PNT321 and PNT540 files, too?
