Hi, I have an IP500 Control Unit running R4.2(11) and the following licenses...
IP500 Upgrade Standard to Professional
Mobility Features
Phone Manager
VMPro TTS (Generic)
Voicemail Pro (4 ports)
I'd like to upgrade this to R8.1 but I'm a little confused on the license requirements. I believe I need a IPO LIC UPG 8.1 upgrade license and an Essential edition license, is this correct and am I missing anything else that I need?
Any advice will be gratefully received.
