Hi.
I’ve got a phone system which I believe was on R9, but has been on R11 for some time. We’ve got a few phones (1416) and when plugging these in it’s showing “Upgrade: file access error”. There are not any other 1416 phones in use.
I’m unsure if I can copy files from an R9 CCU to the R11?
What’s the method for upgrading the phones successfully? Does anyone have the file? Willing for someone to do this remotely at cost if easier.
Cheers.
