Dear Experts,
I have Tandberg endpoints with old versino and I want to upgrade them so it can be natively registered to CUCM.
C20 version is T3.1.2
EX9- version is T3.1.2
E20 I am not sure with version.
I want to upgrade C20 and EX90 to version T7.0 and E20 to version T4.1
what is the required for the upgrade, what is the steps ? is there any intermediate version in the upgrade or we can do direct upgrade to the latest.
Thanks in advance
Anas
