I have kind of a novice question about call security/encryption.
Currently, we do not encrypt calls. To encrypt calls between the phones and CM, it is just as simple as setting the Enterprise Paramter for Device Security Mode to Encrypted and then resetting all phones? (All phones' Device Security Modes are already set to use System Default.)
This seems too simple, which is why any advice and/or links to config references would be appreciated. Thanks in advance.
