Anybody has NEC SV8100/SL8100 licence manual?
I got one called ‘SV8100 Licensing Manual v2.0',but it just has few licences' explanations.

Yesterday I tried to use 3CX on the phone system with '5301 softphone x4', it didn't work. It did work if temporary licences turned on. So we GUESS maybe '5301 softphone' and '5303 soft phone enhanced' are both needed.

We are always confronted with the licence issues, and want to know what's the licence used for or what kinds of licences needed.
