They have been rock solid and in all my time doing PBX, they are my absolute favourite systems. Really sad to see them go.
They have also been more than fair in offering to open up all licenced features free of charge from 2022 for all the current systems. I don't know of another manufacturer who has ever done this after retiring.
Q1-5: We have long-term maintenance contracts with end customers therefore it is important that activation keys can still be ordered after December 2022.
A1-5: Panasonic will provide a firmware update in 2022 that will enable all capacity and functionality without the need to purchase and install activation keys. Please note that the firmware will only be made available for the NS, NSX and NSV platforms.
