I am working on an IP office 500 V2. I have two cards installed: ATM4U & DS 1-8. I am attempting to install a new combo card but this is not working out. I am getter a configuration alarm; invalid card fitted. The card i am trying to deploy is; ATM4V2
The release of software on the PBX is 8.1(69)
Can anyone add clarity or give me some advice.
